Description

Technical Field

[0001] This invention relates to the field of self-propelled sling drive technology, and in particular to a self-propelled sling drive mechanism, a self-propelled sling and cable hoisting system. Background Technology

[0002] Traditional long-span arch bridges are mainly constructed using cable cranes. Specifically, a cable crane includes a load-bearing cable and a trolley system. The trolley system is connected to a hook assembly via a lifting cable and is used to lift the load. Cable cranes are equipped with towers at both ends, with cable saddles on the towers. A support cable is installed between the trolley system and the towers. The load-bearing cable passes through the cable saddles of the towers at both ends and is anchored to the ground. The load-bearing cable provides the running track for the trolley system and the support cable. Each trolley traction cable and each lifting cable is mainly steered by the cable saddle wheel assembly on the tower cable saddle and tensioned and unloaded by their respective winches. This allows the trolley traction cable to enable the trolley system to travel along the bridge direction, and the lifting cable to enable the vertical movement of the lifted object.

[0003] Currently, in the operation of traditional long-span arch bridge cable cranes, each lifting cable, traction cable, and load-bearing cable adopts a passive support system. In the passive support system, each support is set in front of and behind the trolley of the cable crane along the length of the lifting cable. The trolley directly pushes or pulls each support. However, the existing supports are all traction supports, which have the defect of excessive drooping and excessive length of ropes, making them prone to tangling.

[0004] The applicant's research team discovered that the commonly used single-main-rope self-propelled support system for water and cable cables operates on the following transmission method: two traction cable pressure rollers press the traction cable tightly, causing it to adhere closely to the friction wheel below. When the traction cable moves, the friction wheel rotates under the action of friction, which in turn drives the chain. Through a two-stage transmission, the power is transmitted to the traveling wheel, causing the traveling wheel to roll on the supporting cable, thus enabling the support system to move. However, this self-propelled support system has the following drawbacks:

[0005] (1) The two traction cable pressure rollers press the traction cable tightly onto the friction wheel, which is prone to slippage and poses a risk of use;

[0006] (2) The two traction cable pressure rollers press the traction cable tightly onto the friction wheel, which involves many structures and is complex.

[0007] (3) The two traction cable pressure rollers press the traction cable onto the friction wheel, occupying the upper space of the friction wheel. This requires a two-stage transmission to transfer power from the friction wheel to the traveling wheel, resulting in low transmission efficiency, complex structure, and lower stability. Summary of the Invention

[0008] The purpose of this invention is to address the problems of existing self-propelled sling systems, such as slippage due to two pressure rollers pressing the traction cable onto the friction roller, posing a risk of use, and the low transmission efficiency, complex structure, and lower stability of the two-stage transmission method used to transfer power from the friction roller to the traveling wheel. This invention provides a transmission mechanism for a self-propelled sling system, a self-propelled sling system, and a cable-stayed system.

[0009] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0010] A self-propelled support cable transmission mechanism includes a traction cable, a first friction wheel, a second friction wheel, a first sprocket, a chain, a second sprocket, a traveling wheel, and a transmission bracket;

[0011] The first friction wheel, the second friction wheel, the first sprocket, the second sprocket, and the traveling wheel are all rotatably mounted on the transmission bracket. The rotation axes of the first friction wheel, the second friction wheel, the first sprocket, the second sprocket, and the traveling wheel are all arranged along a first direction. The first sprocket and the first friction wheel are coaxially arranged and can rotate synchronously. The second sprocket and the traveling wheel are coaxially arranged and can rotate synchronously. The traveling wheel cooperates with the upper side of the carrying cable. The first sprocket and the second sprocket are connected by the chain drive.

[0012] The traction cable includes an entry section, an exit section, and a winding section. The winding section is located between the corresponding entry and exit sections, and the winding section is wound in a loop on at least the first friction wheel and the second friction wheel.

[0013] In this design, the entry section of the traction cable refers to the part that enters the self-propelled support in the second direction, and the exit section refers to the part that exits from the self-propelled support in the second direction. The winding section is wound around the first friction wheel and the second friction wheel, forming a loop under the support of the first friction wheel and the second friction wheel, thereby providing tension and ensuring that the traction cable is always located on the first friction wheel, which can drive the first friction wheel to rotate. Because the first sprocket is coaxial with the first friction wheel, the first sprocket and the first friction wheel can rotate synchronously, so that the rotation of the first friction wheel drives the rotation of the first sprocket.

[0014] Because the first sprocket and the second sprocket are connected by the chain drive, the rotation of the first sprocket drives the rotation of the second sprocket. Because the second sprocket and the traveling wheel are coaxially arranged, the second sprocket and the traveling wheel can rotate synchronously, so that the rotation of the second sprocket drives the rotation of the traveling wheel, thereby allowing the traveling wheel to roll on the carrying cable. The rotation axes of the first friction wheel, the second friction wheel, the first sprocket, the second sprocket and the traveling wheel are all arranged in the same direction. The transmission bracket of the self-propelled cable support mechanism is fixedly arranged on the cable support frame, thereby allowing the self-propelled cable support to move along the traction cable direction on the carrying cable.

[0015] Existing self-propelled stay devices use a pressure roller to press the traction cable against a friction wheel, which is prone to slippage. The self-propelled stay device transmission mechanism of this invention uses a section of the traction cable wound around at least the first and second friction wheels to form a loop. The traction cable drives the first friction wheel, which in turn drives the traveling wheel to rotate. Guided by the first and second friction wheels, the traction cable maintains tension, reducing the likelihood of slippage. Furthermore, existing self-propelled stay devices use a two-stage transmission to allow the traveling wheel to roll on the support cable, enabling forward movement. However, this method is complex, has a high failure rate, low transmission reliability, and low transmission efficiency. This application uses a first and second friction wheel to form a loop around the traction cable, freeing up space around the first friction wheel. The first sprocket is concentric with the first friction wheel, and the second sprocket is concentric with the traveling wheel. The first and second sprockets are driven by a chain, requiring only a single stage of transmission to ensure high efficiency. This transmission mechanism is simpler, has a lower failure rate, and offers strong reliability.

[0016] As a preferred embodiment of the present invention, the winding section of the traction cable only wraps around the first friction wheel and the second friction wheel once, requiring fewer friction wheels, making installation more convenient, transmission simpler, and use more reliable.

[0017] As a preferred embodiment of the present invention, the transmission bracket is provided with a mounting base, the mounting base is provided with a second strip-shaped hole, the length direction of the second strip-shaped hole is a second direction, the second direction is perpendicular to the first direction, the second direction is the axial direction of the carrying cable, and a chain clamping wheel is detachably and rotatably connected to the second strip-shaped hole, the chain clamping wheel is used to clamp the chain, and the chain clamping wheel can rotate with the chain.

[0018] By installing a chain tensioning wheel on the transmission bracket to tighten the chain, chain slack can be prevented. Furthermore, the mounting base has a second strip-shaped hole along its length, allowing the chain tensioning wheel to be installed at different positions within the second strip-shaped hole, accommodating different types of chains.

[0019] A self-propelled cable support includes a cable support frame and a transmission mechanism. The transmission support of the transmission mechanism is connected to the cable support frame. The cable support frame is provided with at least one set of traction cable guide wheels and at least one set of main cable guide wheels. The axial direction of the traction cable guide wheels is the same as the axial direction of the first friction wheel of the transmission mechanism. The axial direction of the main cable guide wheels is the same as the axial direction of the first friction wheel. The traction cable passes between all the sets of traction cable guide wheels, and the load-bearing cable passes between all the sets of main cable guide wheels.

[0020] The self-propelled cable support described in this invention employs the transmission mechanism described in this invention, which makes the movement of the self-propelled cable support on the load-bearing cable more stable and safe, and also has high transmission efficiency and lower energy consumption.

[0021] As a preferred embodiment of the present invention, it further includes a clutch mechanism, which includes a force-relieving mechanism, a striker, a first clutch rotating shaft, a second clutch rotating shaft, and a third clutch rotating shaft, wherein the axial directions of the first clutch rotating shaft, the second clutch rotating shaft, and the third clutch rotating shaft are all in a first direction;

[0022] The firing pin is positioned in a second direction, which is the axial direction of the carrying cable. The unloading mechanism is positioned in the height direction. The height direction, the second direction, and the first direction are perpendicular to each other. The unloading mechanism includes an integrally formed long arm and a short arm. One end of the long arm is rotatably connected to the firing pin via the third clutch rotating shaft. The other end of the long arm is connected to the short arm. The short arm and the long arm form an angle in the height direction. The firing pin and the short arm are located on opposite sides of the long arm in the second direction. The firing pin is positioned outward in the second direction, and the short arm is positioned inward in the second direction. The point where the long arm and the short arm meet is the first intersection point. The first intersection point is rotatably connected to the transmission bracket via the second clutch rotating shaft. A support wheel is rotatably mounted on the end of the short arm away from the long arm. The rotation axis of the support wheel is in the first direction. The cable support frame has a support rod positioned along the second direction. The support wheel rolls upward or downward to support the support rod positioned along the second direction.

[0023] The transmission bracket and the cable support frame are rotatably connected via the first clutch rotating shaft.

[0024] A trolley is mounted on the load-bearing cable, and several self-propelled support devices are spaced apart on both sides of the trolley along a second direction. When the firing pin of one self-propelled support device strikes another, a force is generated inward in the second direction, causing the long arm of the unloading mechanism to rotate around a third clutch axis. This, in turn, drives the short arm to rotate around a second clutch axis, causing the support wheel at the end of the short arm to roll and move on the support rods set in the second direction of the support frame, maintaining support at all times. Due to the rotation direction of the short arm, its support length changes, causing the transmission bracket to change its positional relationship with the support frame around the first clutch axis. The positional relationship between the load-bearing cable and the support frame remains relatively fixed. This change in the positional relationship between the transmission bracket and the load-bearing cable causes the trolley wheel to disengage from the load-bearing cable, preventing the self-propelled support device from moving further and avoiding further impact damage. The support rods serve as the support structure and moving track for the support wheel, limiting the rolling direction of the support wheel and ensuring the stability of the clutch mechanism.

[0025] As a preferred embodiment of the present invention, the cable frame has a cable rod arranged along the height direction, the cable rod arranged along the height direction is provided with a guide cylinder, and the guide cylinder is arranged along a second direction;

[0026] A first strip-shaped hole is provided at the position where the long arm connects to the firing pin, and the first strip-shaped hole is provided along the length direction of the long arm;

[0027] After passing through the guide cylinder, the firing pin is rotatably connected to the first strip hole via the third clutch rotating shaft.

[0028] The guide tube restricts the height of the firing pin, ensuring a constant force direction after impact and improving reliability. The first slot allows the third clutch shaft to reposition, improving force relief and meeting the rotational requirements of the force-relieving mechanism.

[0029] As a preferred embodiment of the present invention, the cable support frame has a cable support rod arranged along the second direction, and the transmission support has a support rod arranged along the second direction;

[0030] A clamping mechanism is provided between the support rod and the bracket rod arranged in the second direction. The clamping mechanism includes a pull rod, a spring, a pressure block and a locking part. The pull rod is arranged in the height direction. The pressure blocks are respectively provided on the corresponding support rod and bracket rod. The pressure blocks and the locking part are both passed through the pull rod. The spring is provided between the pressure block and the locking part corresponding to the bracket rod.

[0031] The spring presses the corresponding support rod against the corresponding support cable rod, so that the traveling wheel can be pressed against the load-bearing cable.

[0032] The clamping mechanism utilizes the spring force to ensure that the traveling wheel is pressed against the load-bearing cable, improving the stability of the traveling wheel's movement on the load-bearing cable and making it more reliable. Furthermore, after the impact of the firing pin, the traveling wheel detaches from the load-bearing cable, and under the spring's rebound, the traveling wheel can gradually return to the load-bearing cable, allowing for continued movement and use.

[0033] In a preferred embodiment of the present invention, the first friction wheel and the second friction wheel are spaced apart in a second direction, which is the direction of the bearing cable;

[0034] The first friction wheel and the traveling wheel are spaced apart in the height direction;

[0035] The clutch mechanism is located on the side close to the second friction wheel, and the diameter of the second friction wheel is smaller than the diameter of the first friction wheel.

[0036] The diameter of the second friction wheel is smaller than that of the first friction wheel, and the clutch mechanism is positioned on the side close to the second friction wheel. This avoids interference with the traction cable when the clutch mechanism drives the second friction wheel to move, ensuring that the transmission mechanism can be used normally in the future. It also avoids interference between the rotation of the long arm and the spatial position of the second friction wheel, making the structure more compact while ensuring that the clutch mechanism can be used normally.

[0037] In a preferred embodiment of the present invention, the transmission support includes a first support rod, a second support rod, a third support rod, and a fourth support rod. The first and second support rods are both arranged along a second direction, and both the second and fourth support rods are arranged along a height direction. One end of the second support rod is connected to one end of the third support rod. A first friction wheel and a first sprocket are rotatably arranged at the connection between the second and third support rods. The other end of the second support rod is rotatably connected to a traveling wheel and a second sprocket. One end of the fourth support rod is connected to the other end of the third support rod. A second friction wheel is rotatably arranged at the connection between the fourth and third support rods. The other end of the fourth support rod is connected to the first support rod.

[0038] The cable support frame includes a first cable rod, a second cable rod, and a third cable rod. The first cable rod is arranged along a second direction, and the second and third cable rods are arranged along the height direction. The second and third cable rods are spaced apart in the second direction, and the first cable rod is connected between the second and third cable rods.

[0039] Each of the second and third support rods has at least one set of traction cable guide wheels at one end. The self-propelled support cable transmission mechanism is located between the second and third support rods. The first support rod is connected to the second and / or third support rods. The traction cable enters from one set of traction cable guide wheels at one end of the second support rod, and after the first and second friction wheels have rotated once, it exits from one set of traction cable guide wheels at one end of the third support rod. Each set of traction cable guide wheels limits and guides the traction cable.

[0040] The second and third support cables are each provided with at least one set of main cable guide wheels at their other ends. The carrying cable enters from the set of main cable guide wheels at the other end of the second support cable, passes through the traveling wheel, and then exits from the set of main cable guide wheels at the other end of the third support cable. Each set of main cable guide wheels limits and guides the carrying cable.

[0041] The aforementioned transmission support and cable support frame have a simple and compact structure, making them easy to manufacture and design.

[0042] Preferably, the support frame includes an upper frame and a lower frame. The lower frame is provided with traction cable guide wheel sets at intervals in the second direction. The traction cable guide wheel sets have traction cable guide wheels at intervals in the height direction. The lower frame is provided with the traction cable guide wheel sets in the height direction. The bottom of the lower frame is provided with lifting cable limit wheel sets at intervals in the second direction. The lifting cable limit wheel sets are provided with lifting cable limit wheels in the height direction.

[0043] The upper frame is provided with main cable guide wheel groups at intervals in the second direction, and the main cable guide wheel groups are provided with main cable guide wheels in the height direction, and the main cable guide wheel groups are higher than the traction cable guide wheel groups;

[0044] The transmission bracket connects the upper frame and the lower frame, the traveling wheel is higher than the first friction wheel, and the clamping mechanism is connected to the upper frame and the transmission bracket.

[0045] The hanging method is applied to a single-load cable-stayed system, resulting in greater stability. Preferably, the support frame further includes a support hanger, which is arranged along the height direction and connected to the middle of the first support rod. The support hanger has several sets of lifting cable limiting wheels spaced apart along the height direction. Each set of lifting cable limiting wheels includes two lifting cable limiting wheels, and the two lifting cable limiting wheels in each set are arranged along the height direction. The axial direction of the lifting cable limiting wheels is a first direction.

[0046] When a cable crane has multiple load-bearing cables, the cable hanger can be used to hang the lifting cables of the cable crane.

[0047] A single-load cable crane system includes two traction cables, a load-bearing cable, a lifting cable, a trolley, and a single-load-bearing cable self-propelled support. The trolley is located in the longitudinal middle of the single-load-bearing cable crane system. Self-propelled supports are symmetrically arranged on both sides of the trolley in the longitudinal direction of the single-load-bearing cable crane system. The load-bearing cable is pulled from one end of the single-load-bearing cable crane system to the other end in the longitudinal direction. The self-propelled supports and the trolley are both attached to the load-bearing cable.

[0048] One of the traction cables connects sequentially from the first longitudinal side of the single-bearing cable hoisting system to the traction cable guide wheel assembly above the self-propelled support on the first side, with one end of the traction cable connecting to the cable saddle pulley on the first side and the other end of the traction cable connecting to the first side of the trolley.

[0049] One end of another traction cable is connected to the second side of the vehicle, and the other end of the other traction cable sequentially engages with the traction cable guide wheel assembly above the self-propelled support on the second side, passes over the cable saddle pulley on the second side, engages with the traction cable guide wheel assembly below the self-propelled support on the second side, engages with the vehicle, engages with the traction cable guide wheel assembly below the self-propelled support on the first side and the cable saddle pulley on the first side. The first side and the second side are the longitudinal sides of the single-bearing cable hoisting system.

[0050] The lifting cable is anchored on the second side. From the second side to the first side, the lifting cable sequentially engages with the lifting cable guide wheel assembly at the bottom of the self-propelled support on the second side, engages with the trolley, engages with the lifting cable guide wheel assembly at the bottom of the self-propelled support on the first side, and engages with the cable saddle pulley on the first side.

[0051] The single-load cable hoisting system described in this invention has a simple and compact structure, stable support cables, and high transmission efficiency.

[0052] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0053] 1. The self-propelled support cable transmission mechanism of the present invention involves the traction cable being wound in a loop around at least the first and second friction wheels. The traction cable drives the first friction wheel, which in turn drives the traveling wheel to rotate. Under the guidance of the first and second friction wheels, the traction cable has tension and is not prone to slippage. By using the first and second friction wheels to wound the traction cable in a loop, the space around the first friction wheel is not occupied. The first sprocket and the first friction wheel are concentrically set, and the second sprocket and the traveling wheel are concentrically set. The first and second sprockets are driven by a chain, so only one stage of transmission is needed to ensure transmission. It has high transmission efficiency, a simpler transmission mechanism, a low failure rate, and strong transmission reliability.

[0054] 2. In the self-propelled support cable transmission mechanism of the present invention, the winding section of the traction cable only wraps around the first friction wheel and the second friction wheel once, requiring fewer friction wheels, and is more convenient to install, simpler to transmit, and more reliable to use.

[0055] 3. The self-propelled support cable transmission mechanism of the present invention prevents the chain from becoming loose by setting a chain clamping wheel on the transmission bracket to clamp the chain. Furthermore, the mounting base has a second strip-shaped hole in the second direction along its length, allowing the chain clamping wheel to be installed at different positions within the second strip-shaped hole, thus accommodating the installation of different chains.

[0056] 4. The self-propelled support cable described in this invention uses the transmission mechanism of the self-propelled support cable described in this invention, which makes the movement of the self-propelled support cable more stable and safe, and has high transmission efficiency and lower energy consumption.

[0057] 5. The self-propelled support cable of the present invention, through the combination of the firing pin, the unloading mechanism and the support wheel with the transmission bracket and the support cable frame, forms an unloading clutch mechanism, which allows the traveling wheel to disengage from the load-bearing cable, thereby preventing the self-propelled support cable from continuing to move and avoiding further impact damage.

[0058] 6. The self-propelled support cable of the present invention has a pressure mechanism. The clamping mechanism uses the elastic force of a spring to ensure that the traveling wheel can be pressed onto the support cable, improving the stability of the traveling wheel's movement on the support cable and making it more reliable. Moreover, after the impact of the firing pin, the traveling wheel disengages from the support cable, and under the spring's rebound, the traveling wheel can gradually return to the support cable, allowing it to continue to move and be used subsequently.

[0059] 7. In the self-propelled support device of the present invention, the diameter of the second friction wheel is smaller than that of the first friction wheel, and the clutch mechanism is located on the side close to the second friction wheel to avoid interference with the traction cable when the clutch mechanism drives the second friction wheel to move, ensuring that the transmission mechanism can be used normally in the future, and avoiding interference between the rotation of the long arm and the spatial position of the second friction wheel, so that the structure can be more compact under the premise that the clutch mechanism can be used normally.

[0060] 8. The self-propelled cable support described in this invention also has a cable support bracket. When the cable crane has multiple load-bearing cables, the cable support bracket can be used to hang the lifting cables of the cable crane.

[0061] 9. The single-bearing cable hoisting system of the present invention has a simple and compact structure, stable support cables, and high transmission efficiency. Attached Figure Description

[0085] Example 1

[0086] This embodiment provides a self-propelled support cable drive mechanism; see [link / reference]. Figure 1 It includes a traction cable 3, a first friction wheel 11, a second friction wheel 12, a first sprocket 13, a chain 14, a second sprocket 15, a traveling wheel 16, and a transmission bracket 17;

[0087] The first friction wheel 11, the second friction wheel 12, the first sprocket 13, the second sprocket 15, and the traveling wheel 16 are all rotatably mounted on the transmission bracket 17. The rotation axes of the first friction wheel 11, the second friction wheel 12, the first sprocket 13, the second sprocket 15, and the traveling wheel 16 are all arranged along a first direction. The first sprocket 13 is coaxially arranged with the first friction wheel 11 and can rotate synchronously with the first friction wheel 11. The second sprocket 15 is coaxially arranged with the traveling wheel 16 and can rotate synchronously with the second sprocket 15 and the traveling wheel 16. The traveling wheel 16 cooperates with the upper side of the carrying cable 4. The first sprocket 13 and the second sprocket 15 are connected by the chain 14.

[0088] The traction cable 3 includes an entry section, an exit section, and a winding section. The winding section is located between the corresponding entry and exit sections, and the winding section is wound in a loop at least on the first friction wheel 11 and the second friction wheel 12.

[0089] In this embodiment, the structure of the transmission support 17 can vary, but the key is to ensure that the first friction wheel 11, the second friction wheel 12, the first sprocket 13, the second sprocket 15, and the traveling wheel 16 all have a stable rotational foundation. This means that a rotational shaft can be installed on the transmission support 17, allowing the first friction wheel 11, the second friction wheel 12, the first sprocket 13, the second sprocket 15, and the traveling wheel 16 to rotate on their respective rotational shafts. The self-propelled support can be installed on a cable crane; therefore, the overall direction of the carrying cable 4 and the traction cable 3 is along the longitudinal direction of the bridge, i.e., the second direction. The rotational shafts of the first friction wheel 11, the second friction wheel 12, the first sprocket 13, the second sprocket 15, and the traveling wheel 16 are all arranged along the transverse direction of the bridge, i.e., the first direction. In this embodiment, the diameters of the first friction wheel 11, the first sprocket 13, the second sprocket 15, and the traveling wheel 16 are designed according to the transmission ratio, thereby changing the moving speed of the self-propelled support.

[0090] like Figure 2As shown, in this embodiment, the transmission support 17 includes a first support rod 171, a second support rod 172, a third support rod 173, and a fourth support rod 174. The first support rod 171 and the second support rod 172 are arranged in parallel, both along a second direction. The second support rod 172 and the fourth support rod 174 are both arranged along a height direction. One end of the second support rod 172 is connected to one end of the third support rod 173. The first friction wheel 11 and the first sprocket 13 are rotatably arranged at the connection between the second support rod 172 and the third support rod 173. The other end of the second support rod 172 is rotatably arranged with the traveling wheel 16 and the second sprocket 15. One end of the fourth support rod 174 is connected to the other end of the third support rod 173. The second friction wheel 12 is rotatably arranged at the connection between the fourth support rod 174 and the third support rod 173. The other end of the fourth support rod 174 is connected to the first support rod 171. This transmission bracket 17 has a simple structure and is easy to process. In the first direction, this transmission bracket 17 generally adopts a double-layer structure, which can clamp the first friction wheel 11, the second friction wheel 12, the first sprocket 13, the second sprocket 15 and the traveling wheel 16 in the middle to ensure the stability of their rotation.

[0091] In this embodiment, the entry section of the traction cable 3 refers to the part that enters the self-propelled support in the second direction, and the exit section of the traction cable 3 refers to the part that exits from the self-propelled support in the second direction. The winding section is wound around the first friction wheel 11 and the second friction wheel 12, forming a loop under the support of the first friction wheel 11 and the second friction wheel 12, thereby providing tension and ensuring that the traction cable is always located at the first friction wheel 11, enabling it to drive the first friction wheel 11 to rotate. Because the first sprocket 13 is coaxially arranged with the first friction wheel 11, the first sprocket 13 and the first friction wheel 11 can rotate synchronously, so that the rotation of the first friction wheel 11 drives the rotation of the first sprocket 13. Figure 10 As shown, the traction cable 3 enters the self-propelled cable holder and then exits, before entering the second self-propelled cable holder.

[0092] Because the first sprocket 13 and the second sprocket 15 are connected by the chain 14, the rotation of the first sprocket 13 drives the rotation of the second sprocket 15. Because the second sprocket 15 and the traveling wheel 16 are coaxially arranged, the second sprocket 15 and the traveling wheel 16 can rotate synchronously, so that the rotation of the second sprocket 15 drives the rotation of the traveling wheel 16, thereby allowing the traveling wheel 16 to roll on the carrying cable 4. The rotation axes of the first friction wheel 11, the second friction wheel 12, the first sprocket 13, the second sprocket 15 and the traveling wheel 16 are all arranged in the same direction. The transmission bracket 17 of the self-propelled cable support mechanism is fixedly arranged on the cable support frame 2, thereby allowing the self-propelled cable support to move along the traction cable 3 direction on the carrying cable 4.

[0093] Existing self-propelled stay devices use a pressure wheel to press the traction cable against a friction wheel, which is prone to slippage. In this embodiment, the transmission mechanism of the self-propelled stay device uses a section of the traction cable 3 wound around at least the first friction wheel 11 and the second friction wheel 12 to form a loop. The traction cable 3 drives the first friction wheel 11, which in turn drives the traveling wheel 16 to rotate. Guided by the first and second friction wheels 11 and 12, the traction cable 3 has tension, making it less prone to slippage. Furthermore, existing self-propelled stay devices use a two-stage transmission to allow the traveling wheel to roll on the support cable, enabling the self-propelled stay device to move forward. However, this method is complex, has a high transmission failure rate, low transmission reliability, and low transmission efficiency. This embodiment uses the first friction wheel 11 and the second friction wheel 12 to form a loop around the traction cable, as... Figure 1 As shown, the space around the first friction wheel 11 is not occupied, and the first sprocket 13 is concentrically set with the first friction wheel 11. The second sprocket 15 and the traveling wheel 16 are concentrically set. The first sprocket 13 and the second sprocket 15 are driven by the chain 14, so that only one stage of transmission is needed to ensure transmission. It has high transmission efficiency, and its transmission mechanism is simpler, with a low failure rate and strong transmission reliability.

[0094] As one implementation method, such as Figure 1 As shown, the winding section of the traction cable 3 only wraps around the first friction wheel 11 and the second friction wheel 12 once, requiring fewer friction wheels, making installation more convenient, transmission simpler, and use more reliable.

[0095] This invention relates to a self-propelled sling drive mechanism, used on self-propelled slings, which requires speed regulation: cable cranes have large spans, and the maximum spacing between self-propelled slings is approximately 100m, thus requiring multiple self-propelled slings. During operation, the self-propelled slings form themselves under the same traction cable speed. To ensure even distribution of the slings on the load-bearing cable, the travel speed of each sling should be inconsistent but proportionally controlled. Therefore, the self-propelled sling drive mechanism should be speed-regulated. Speed ​​regulation principle: In each self-propelled sling drive mechanism, the diameters of the first friction wheel, the second friction wheel, and the traveling wheel are the same and fixed. The first sprocket and the second sprocket have different numbers of teeth, i.e., different transmission ratios. By adopting different transmission ratios, different travel speeds are achieved for the traveling wheel. Calculation method: Assuming the ratio of the traveling wheel's diameter to the first friction wheel's diameter is 'a', the transmission ratio of the second sprocket to the first sprocket is 'i', and the traction cable speed is 'v', then the traveling wheel speed V1 = a * i * v.

[0096] As one implementation method, such as Figure 1 , Figure 2 and Figure 3 As shown, the transmission bracket 17 is provided with a mounting base 175, and the mounting base 175 has a second strip-shaped hole 176. The length direction of the second strip-shaped hole 176 is a second direction. A chain tensioning wheel 177 is detachably and rotatably connected to the second strip-shaped hole 176. The chain tensioning wheel 177 is used to tighten the chain 14. By providing a chain tensioning wheel 177 on the transmission bracket 17 to tighten the chain 14, the chain 14 can be prevented from becoming loose. Furthermore, the second strip-shaped hole 176 on the mounting base 175 allows the chain tensioning wheel 177 to be installed at different positions in the second strip-shaped hole 176, accommodating the installation of different chains 14. Specifically, the chain tensioning wheel 177 is fixed to different positions in the second strip-shaped hole 176 by a rotating shaft or bolts, and the chain tensioning wheel 177 can rotate with the chain 14.

[0097] Example 2

[0098] This embodiment provides a self-propelled support device, such as Figure 4 As shown, the device includes a support frame 2 and a self-propelled support drive mechanism as described in Embodiment 1. The drive bracket 17 of the self-propelled support drive mechanism is connected to the support frame 2. The support frame 2 is provided with at least one set of traction cable guide wheels 26 and at least one set of main cable guide wheels 25. The axial direction of the traction cable guide wheels 26 is the same as the axial direction of the first friction wheel 11 of the self-propelled support drive mechanism. The axial direction of the main cable guide wheels 25 is the same as the axial direction of the first friction wheel 11. The traction cable 3 passes between all the sets of traction cable guide wheels 26, and the load-bearing cable 4 passes between all the sets of main cable guide wheels 25.

[0099] In this embodiment, as Figure 4 and Figure 7 As shown, the cable support frame 2 includes a first cable rod 21, a second cable rod 22, and a third cable rod 23. The first cable rod 21 is arranged along a second direction, and the second cable rod 22 and the third cable rod 23 are arranged along the height direction. The second cable rod 22 and the third cable rod 23 are distributed at intervals in the second direction, and the first cable rod 21 is connected between the second cable rod 22 and the third cable rod 23.

[0100] At least one set of traction cable guide wheels 26 are provided at one end of the second support rod 22 and the third support rod 23. The self-propelled support cable transmission mechanism is located between the second support rod 22 and the third support rod 23. The first support rod 171 is connected to the second support rod 22 and / or the third support rod 23. The traction cable 3 enters from one set of traction cable guide wheels 26 at one end of the second support rod 22, and after the first friction wheel 11 and the second friction wheel 12 have been wound around once, it is led out from one set of traction cable guide wheels 26 at one end of the third support rod 23. Each set of traction cable guide wheels 26 limits and guides the traction cable 3.

[0101] The second support cable 22 and the third support cable 23 are each provided with at least one set of main cable guide wheels 25. The carrying cable 4 enters from the set of main cable guide wheels 25 at the other end of the second support cable 22, passes through the traveling wheel 16, and then exits from the set of main cable guide wheels 25 at the other end of the third support cable 23. Each set of main cable guide wheels 25 limits and guides the carrying cable 4.

[0102] In this embodiment, as Figures 4-6 As shown, the self-propelled support device is equipped with a clutch mechanism 18, which includes a force-relieving mechanism 181, a firing pin 182, a first clutch rotating shaft 184, a second clutch rotating shaft 185, and a third clutch rotating shaft 186. The axial directions of the first clutch rotating shaft 184, the second clutch rotating shaft 185, and the third clutch rotating shaft 186 are all in the first direction.

[0103] The firing pin 182 is positioned in a second direction, which is the axial direction of the carrying cable 4. The unloading mechanism 181 is positioned in the height direction. The height direction, the second direction, and the first direction are perpendicular to each other. The unloading mechanism 181 includes an integrally formed long arm 1811 and a short arm 1812. One end of the long arm 1811 is rotatably connected to the firing pin 182 via the third clutch rotating shaft 186. The other end of the long arm 1811 is connected to the short arm 1812. The short arm 1812 and the long arm 1811 have an angle in the height direction. The firing pin 182 and the short arm 1812 are respectively located on both sides of the long arm 1811 in the second direction. The second direction is outward, the short arm 1812 is inward in the second direction, the long arm 1811 and the short arm 1812 are connected at the first intersection point, the first intersection point is rotatably connected to the transmission bracket 17 through the second clutch rotating shaft 185, the end of the short arm 1812 away from the long arm 1811 is rotatably provided with a support wheel 1813, the rotation axis of the support wheel 1813 is in the first direction, the cable frame 2 has a cable rod arranged along the second direction, that is, the first cable rod 21, the support wheel 1813 rolls upward or downward to support the first cable rod 21, and the transmission bracket 17 and the cable frame 2 are rotatably connected through the first clutch rotating shaft 184.

[0104] Specifically, in this embodiment, a connecting rod 27 is provided on the second support rod 22 or the third support rod 23. The connecting rod 27 is located above the first support rod 21 and is cantilevered between the second support rod 22 and the third support rod 23. One end of the first support rod 171 is rotatably connected to the connecting rod 27 through the first clutch rotating shaft 184, so that the transmission support 17 and other components provided on the transmission support 17 can rotate around the first clutch rotating shaft 184. The other end of the first support rod 171 is rotatably connected to the unloading mechanism 181 through the second clutch rotating shaft 185.

[0105] In cable cranes, the carrying cable has a trolley, which is not shown in the accompanying drawings. Several self-propelled support devices are spaced apart on both sides of the trolley along a second direction. Figure 10As shown, when the firing pin 182 of the self-propelled grapple collides with another self-propelled grapple, a force is generated in the second direction towards the inside of the self-propelled grapple. This causes the long arm 1811 of the unloading mechanism 181 to rotate around the third clutch rotation shaft 186, which in turn drives the short arm 1812 to rotate around the second clutch rotation shaft 185. This causes the support wheel 1813 at the end of the short arm 1812 to roll and move on the grapple rod set in the second direction of the grapple frame 2, and to always maintain support. Due to the rotation direction of the short arm 1812, its support length changes, causing the transmission bracket 17 to change its positional relationship with the grapple frame 2 with the first clutch rotation shaft 184 as the pivot. The positional relationship between the load-bearing cable and the grapple frame remains relatively fixed. That is, changing the positional relationship between the transmission bracket 17 and the load-bearing cable causes the traveling wheel to disengage from the load-bearing cable, preventing the self-propelled grapple from continuing to move and avoiding further impact damage. The support rod serves as the support structure and moving track for the support wheel 1813, restricting the rolling direction of the support wheel 1813 and ensuring the stability of the clutch mechanism.

[0106] like Figure 4 and Figure 10 As shown, the support frame 2 is provided with a pad 29 corresponding to the firing pin 182. The pad 29 and the firing pin 182 are located on opposite sides of the support frame 2 in the second direction. That is, when the firing pin 182 strikes an adjacent self-propelled support, it will strike the pad 29 of the adjacent self-propelled support, which can relieve force and avoid stress concentration. Figure 4 When the firing pin 182 strikes the pad 29 of the adjacent self-propelled support cable to the right, the firing pin 182 is subjected to a force to the left and moves to the left. Under the action of the third clutch rotating shaft 186, the long arm 1811 of the unloading mechanism 181 rotates to the right around the third clutch rotating shaft 186. Under the restriction of the second clutch rotating shaft 185, the short arm 1812 rotates to the right around the second clutch rotating shaft 185. The support wheel 1813 moves to the right under the support of the first support cable rod 21, which increases the support height of the short arm 1812 in the height direction. As a result, under the support of the first support cable rod 21, the first support rod 171 is raised upward, causing the traveling wheel 16 to disengage from the load-bearing cable 4. The self-propelled support cable cannot continue to move, avoiding further impact damage.

[0107] Furthermore, the support frame 2 has a third support rod 23 arranged along the height direction, and the third support rod 23 is provided with a guide cylinder 183, which is arranged along a second direction; the long arm 1811 has a first strip hole 1814 at the position where it connects to the striker 182, and the first strip hole 1814 is arranged along the length direction of the long arm 1811; the striker 182 passes through the guide cylinder 183 and is rotatably connected to the first strip hole 1814 through the third clutch rotating shaft 186. The guide cylinder 183 can limit the height position of the striker 182, so that the force direction of the striker 182 after impact is constant, which is more reliable. The first strip hole 1814 allows the third clutch rotating shaft 186 to change position, better unload force, and can meet the rotation requirements of the unloading mechanism 181.

[0108] Furthermore, such as Figure 4 , Figure 8 and Figure 9 As shown, the cable support frame 2 has a first cable support rod 21 arranged along the second direction, and the transmission support 17 has a first support rod 171 arranged along the second direction;

[0109] A clamping mechanism 5 is provided between the first support rod 21 and the first support rod 171. The clamping mechanism 5 includes a pull rod 51, a spring 52, a pressure block 53, and a locking part 54. The pull rod 51 is arranged along the height direction. The pressure blocks 53 are respectively provided on the corresponding support rods and support rods. The pressure blocks 53 and the locking part 54 are both passed through the pull rod 51. The spring 52 is provided between the pressure block 53 and the locking part 54 corresponding to the support rod. The spring 52 presses the corresponding support rod against the corresponding support rod, so that the traveling wheel 16 can be pressed onto the bearing cable 4. In this embodiment, a spherical washer is provided between the pressure block 53 and the first support rod 21 and the first support rod 171. Through the spherical connection, it can cooperate with the first support rod 171 to rotate around the first clutch rotation axis 184 when the clutch mechanism is activated. The clamping mechanism 5 utilizes the elastic force of the spring 52 to ensure that the traveling wheel 16 is pressed against the support cable 4, improving the stability of the traveling wheel 16's movement on the support cable 4 and making it more reliable. Furthermore, after the impact of the firing pin, the traveling wheel 16 disengages from the support cable 4, and under the spring's rebound, the traveling wheel 16 can gradually return to the support cable 4, allowing it to continue moving and being used subsequently.

[0110] Based on the clutch mechanism, another implementation exists where the first friction wheel 11 and the second friction wheel 12 are spaced apart in a second direction, which is the direction of the carrying cable 4; the first friction wheel 11 and the traveling wheel 16 are spaced apart in the height direction; the clutch mechanism 18 is located near the second friction wheel 12, and the diameter of the second friction wheel 12 is smaller than the diameter of the first friction wheel 11. This avoids interference with the traction cable when the clutch mechanism 18 moves the second friction wheel 12, ensuring the normal operation of the transmission mechanism and preventing interference between the rotation of the long arm 1811 and the spatial position of the second friction wheel 12. This allows for a more compact structure while ensuring the normal operation of the clutch mechanism 18. Specifically, the first friction wheel 11 and the second friction wheel 12 are spaced apart along the length of the carrying cable 4, and the traveling wheel 16 is located below or above the first friction wheel 11. The axes of the first friction wheel 11, the second friction wheel 12, and the traveling wheel 16 are located at the three corners of a right triangle. The traction cable 3 enters from above the outer side of the first friction wheel 11, passes in sequence around the upper side of the first friction wheel 11, the upper side of the second friction wheel 12, the outer side of the second friction wheel 12, the lower side of the second friction wheel 12, the lower side of the first friction wheel 11, the outer side of the first friction wheel 11, and the upper side of the first friction wheel 11, and then exits from above the second friction wheel 12.

[0111] In this embodiment, as Figure 4 As shown, when the cable crane has multiple load-bearing cables, the support frame 2 further includes a support frame 24. The support frame 24 is arranged along the height direction and is connected to the middle of the first support rod 21. The support frame 24 is provided with several sets of lifting cable limiting wheels 28 at intervals along the height direction. Each set of lifting cable limiting wheels 28 includes two lifting cable limiting wheels 28, and the two lifting cable limiting wheels 28 in each set are arranged along the height direction. The axial direction of the lifting cable limiting wheels 28 is the first direction. The support frame 24 can be used to hang the lifting cables 6 of the cable crane.

[0112] Example 3

[0113] This embodiment provides a self-propelled support cable device, specifically a single-load-bearing self-propelled support cable device, which eliminates the need for a support cable hanger 24. Based on embodiment 2, as... Figures 11-15 As shown, the cable support frame 2 includes an upper frame body 71 and a lower frame body 72, as... Figure 14 As shown, the lower frame 72 is provided with traction cable guide wheel sets at intervals in the second direction. Each traction cable guide wheel set has traction cable guide wheels 26 spaced at intervals in the height direction. The lower frame 72 is provided with the traction cable guide wheel sets in the height direction. The bottom of the lower frame is provided with lifting cable limiting wheel sets at intervals in the second direction. Each lifting cable limiting wheel set has lifting cable limiting wheels 28 spaced at intervals in the height direction. Figure 11and Figure 13 As shown;

[0114] The upper frame 71 is provided with main cable guide wheel sets at intervals in the second direction, and the main cable guide wheel sets are provided with main cable guide wheels 25 in the height direction, such as... Figure 11 and Figure 12 As shown, the main cable guide wheel assembly is higher than the traction cable guide wheel assembly;

[0115] The transmission bracket 17 connects the upper frame 71 and the lower frame 72. The traveling wheel is higher than the first friction wheel 11. The clamping mechanism is connected to the upper frame 71 and the transmission bracket 17. In this embodiment, the single-bearing cable self-propelled support is applied to a single-bearing cable hoisting system using a hanging method, resulting in greater stability.

[0116] Optional, such as Figure 11 and Figure 14 As shown, a corresponding carrying cable limiting wheel 711 is also provided for the traveling wheel 16. The traveling wheel 16 is located above the carrying cable, and the carrying cable limiting wheel 711 is located below the carrying cable. This can reduce the downward deflection of the carrying cable and ensure that both the trolley and the support cable can travel stably on the carrying cable.

[0117] Example 4

[0118] This embodiment provides a single-load cable hoisting system; see [link / reference]. Figure 16 The system includes two traction cables 3, a load-bearing cable 4, a lifting cable 6, a trolley 75, and a single load-bearing cable self-propelled support. The trolley 75 is located in the longitudinal middle of the single load-bearing cable crane system. The trolley 75 is symmetrically equipped with self-propelled supports on both sides of the longitudinal direction of the single load-bearing cable crane system. The load-bearing cable 4 is pulled from one end of the longitudinal direction of the single load-bearing cable crane system to the other end. The self-propelled support and the trolley 75 are both attached to the load-bearing cable 4.

[0119] One of the traction cables 3 is connected to the traction cable guide wheel group above the self-propelled support above the first side of the single-bearing cable hoisting system in sequence, and one end of the traction cable 3 is connected to the cable saddle pulley 74 on the first side, and the other end of the traction cable 3 is connected to the first side of the trolley 75.

[0120] One end of another traction cable 3 is connected to the second side of the trolley 75, and the other end of the other traction cable 3 is sequentially engaged with the traction cable guide wheel assembly above the self-propelled support on the second side, passes over the cable saddle pulley 74 on the second side, engages with the traction cable guide wheel assembly below the self-propelled support on the second side, engages with the trolley 75, engages with the traction cable guide wheel assembly below the self-propelled support on the first side and the cable saddle pulley 74 on the first side. The first side and the second side are the longitudinal sides of the single-bearing cable hoisting system. Figure 16 In the middle, the left side is the first side, and the right side is the second side.

[0121] The lifting cable 6 is anchored on the second side. From the second side to the first side, the lifting cable 6 sequentially engages with the lifting cable guide wheel assembly at the bottom of the self-propelled support on the second side, the trolley 75, the lifting cable guide wheel assembly at the bottom of the self-propelled support on the first side, and the cable saddle pulley 74 on the first side.

[0122] The single-load-bearing cable hoisting system of the present invention uses the movement of a trolley to drive the traction cable 3 to move left and right, which in turn drives the support cable to move left and right, so that the single-load-bearing cable self-propelled support cable can always support the cable stably, ensuring the stable use of the lifting cable. Its structure is simple and compact, the support cable is stable, and the transmission efficiency is high.

[0123] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
