Description

Technical Field

[0001] The invention relates to a cable crane, in particular to a cable crane sports car. Background Art

[0002] At present, the sports car used for lifting heavy objects in cable cranes is the core component of cable cranes, and certain research has been conducted on the sports car in the field. For example, the patent publication number is CN107265302A, which discloses a double sports car for cable cranes, including two single sports cars, the single sports cars include a load-bearing bracket and a lifting bracket, the load-bearing bracket includes a plurality of inverted triangular load-bearing frame plates arranged side by side, the two upper corners of the load-bearing frame plates are respectively fixed with a load-bearing shaft that sequentially passes through each of the load-bearing bracket plates, the load-bearing shaft is provided with a plurality of load-bearing wheels, the load-bearing wheels are respectively installed between two adjacent load-bearing frame plates, the lifting bracket includes a plurality of lifting bracket plates arranged side by side, the The upper end of the lifting bracket is provided with a load-bearing long axis that sequentially passes through each of the lifting bracket plates, the lifting bracket is hinged to the lower corner of each of the load-bearing frame plates through the load-bearing long axis, the lower end of the lifting bracket is provided with a lifting wheel between two adjacent lifting bracket plates, the lifting bracket is provided with a lifting cable guide wheel, the lifting cable guide wheel is arranged between the load-bearing long axis and the lifting wheel, an intermediate connecting rod is provided on the inner sides of the two single sports cars, the two ends of the intermediate connecting rod are respectively hinged to the load-bearing brackets of the two single sports cars, a connecting rod is provided between the lifting brackets of the two single sports cars, and a traction frame is respectively provided on the outer sides of the load-bearing brackets of the two single sports cars, and the traction frame is rotatably installed with a horizontally arranged traction wheel.

[0003] But there are some problems with the above structure.

[0004] 1. During the installation process, the cable crane sports car needs to install load-bearing wheels, load-bearing frames (inverted triangle plates), load-bearing shafts and other components one by one. Due to the large number of main cables and large lateral width of large-span arch bridges, there are many load-bearing frames and load-bearing wheels, and one load-bearing shaft needs to pass through all the load-bearing wheels and load-bearing frames, resulting in a very long load-bearing shaft. It is difficult to accurately align the various apertures of the load-bearing shaft, load-bearing wheels and load-bearing frames, resulting in a series of problems such as low construction efficiency and great construction difficulty.

[0005] 2. The connecting pin between the load-bearing bracket and the lifting bracket passes through all the load-bearing bracket plates and the lifting bracket plates, which makes the connecting pin very long. It is difficult to accurately align the connecting pin with the hole diameters of the load-bearing bracket plate and the lifting bracket plate, resulting in a series of problems such as low construction efficiency and great construction difficulty. Summary of the invention

[0006] The purpose of the present invention is to provide a cable crane sports car in view of the fact that in the background technology, the connecting pin between the load-bearing bracket and the lifting bracket of a cable crane sports car passes through all the load-bearing bracket plates and the lifting bracket plates, resulting in a very long connecting pin, and it is difficult to accurately align the connecting pin with the hole diameters of the load-bearing bracket plate and the lifting bracket plate, resulting in a series of problems such as low construction efficiency and great construction difficulty.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is:

[0008] A cable crane sports car comprises a lower sports car, a transition frame and at least two upper sports cars, wherein the upper sports cars include

[0009] At least two pulley block frames, on which a plurality of travel pulleys are mounted;

[0010] At least two connecting frames connected between adjacent pulley assembly frames, the adjacent connecting frames are spaced apart along the axial direction of the walking pulley, and the connecting frames are hinged to the transition frame through a first pin shaft;

[0011] The lower sports car is connected to the transition frame.

[0012] The cable crane sports car described in the present application comprises at least two pulley block frames, on which a plurality of walking pulleys are installed; a plurality of walking pulleys installed on the pulley block frames, all of the walking pulleys on the same pulley block frame are coaxially arranged, and the walking pulley is used to cooperate with the cable so that the upper sports car can move in cooperation with the cable on the cable, and at least two connecting frames are arranged between adjacent pulley block frames, and are connected to the transition frame through the connecting frames, so as to achieve the purpose of connecting the lower sports car with the upper sports car. There are at least two connecting frames, and the connecting frames and the transition frame are hinged by a first pin shaft. Compared with the existing through-axis connection method, the cable crane sports car described in the present application comprises an upper sports car and a transition frame that are hinged by at least two first pin shafts, which effectively reduces the unit length of the connecting pin shaft between the upper sports car and the lower sports car, thereby effectively reducing the difficulty of installing and disassembling the cable crane sports car.

[0013] Preferably, all the first pin shafts on the same upper sports car are coaxially arranged.

[0014] Preferably, the pulley block frame is an integral component.

[0015] The existing sports car is to assemble multiple walking pulleys and multiple inverted triangle plates in sequence, and then string them together through pins. However, due to the large number of inverted triangle plates and walking pulleys, the efficiency of stringing the pins one by one is very low, and it is difficult to accurately align them. Based on this, the pulley assembly frame described in the present application is an integral component. During assembly, it is only necessary to position the middle hole of the walking pulley to meet the requirements, which saves construction time and improves construction efficiency.

[0016] At the same time, since the inverted triangle plate and the walking pulley of the sports car in the prior art are strung together one by one through the pin shaft, the lateral displacement of the walking pulley along the length direction of the pin shaft has a cumulative error, and the cable is prone to lateral movement, resulting in uneven load distribution and difficulty in ensuring structural safety. The pulley assembly frame described in the present application is an integral component, so that there is no cumulative displacement between the walking pulleys along the lateral direction of the cable, which can better limit the lateral movement of the cable and better ensure the structural safety.

[0017] In addition, the pulley block frame is made into an integral type to increase the overall weight of the upper sports car or the cable crane sports car, thereby effectively limiting the lateral movement of the cable.

[0018] The cable in the above scheme is generally the main cable of the cable crane.

[0019] Preferably, all the pulley assembly frames and connecting frames on the same upper sports car form an integral component.

[0020] Preferably, at least two of the upper sports cars are connected only by the transition frame.

[0021] The existing sports car is to assemble multiple walking pulleys and multiple inverted triangle plates in sequence. The multiple inverted triangle plates are in the form of scattered sheets. The rigidity of the sports car after being connected cannot be guaranteed and the deformation is large. Therefore, an intermediate connecting rod (located above the cable) is set between the two existing sports cars. In the cable crane sports car described in the present application, the form of assembling the walking pulley on the pulley assembly frame can ensure the overall rigidity and stability of the upper sports car. At least two of the upper sports cars are connected only by the transition frame, which can also meet the use requirements, thereby reducing the number of parts, saving assembly time, reducing costs, and improving construction efficiency.

[0022] Preferably, the first pins on adjacent upper sports cars are arranged in parallel.

[0023] Preferably, one of the upper sports cars is the first upper sports car, and another of the remaining upper sports cars is the second upper sports car, and the transition frame includes two longitudinal beams arranged at intervals, and at least two upwardly protruding connecting parts are provided on the longitudinal beams, at least one of the connecting parts is hinged to the connecting frame on the first upper sports car through a first pin shaft, and at least one of the remaining connecting parts is hinged to the connecting frame on the second upper sports car through a first pin shaft, and adjacent longitudinal beams are fixedly connected.

[0024] Preferably, a traction steering wheel assembly is hinged at the end of the transition frame, and the traction steering wheel assembly includes a steering wheel frame body and at least two traction pulleys arranged on the steering wheel frame body, and the traction pulley is rotatably matched with the steering wheel frame body through a first rotating shaft, wherein at least two of the first rotating shafts are relatively fixed.

[0025] In a cable crane sports car described in the present application, at least two of the first rotating shafts are relatively fixed, so that the corresponding traction pulleys are relatively fixed in the direction of the line connecting the two first rotating shafts, thereby avoiding collision or friction between the mounting seats of the two traction pulleys when running on double lines, effectively ensuring construction safety.

[0026] Preferably, the traction steering wheel assembly also includes a first swinging member, the first swinging member is arranged corresponding to the longitudinal beam, and the first swinging member and the longitudinal beam are vertically hinged through a fifth pin shaft, all the fifth pin shafts are coaxially arranged, the steering wheel frame body and each of the first swinging members are hinged through a second pin shaft, and there is an angle between the second pin shaft and the fifth pin shaft.

[0027] During the construction process, the traction rope bypassing the traction pulley usually applies a tilting force along the direction of the fifth pin to the traction steering wheel assembly, which will apply a bending moment along the direction of the second rotation axis to the traction steering wheel assembly. When the traction steering wheel assembly becomes a whole, the fifth pin will be pulled out axially outward or inward, thereby increasing the probability of damaging the fifth pin or the second ear plate matched with the fifth pin. Therefore, a first swinging member is provided as a transition structure between the longitudinal beam and the steering wheel frame body, the first swinging member is hinged to the longitudinal beam through the fifth pin, the steering wheel frame body and each of the first swinging members are hinged through the second pin, and an angle is formed between the second pin and the fifth pin. The bending moment along the direction of the fifth pin can be released within a certain angle range, effectively reducing the probability of avoiding damaging the fifth pin or the second ear plate matched with the fifth pin.

[0028] Specifically, the second pin axis is perpendicular to the fifth pin axis.

[0029] Specifically, the longitudinal beam is provided with a first through hole which is clearance-matched with the fifth pin shaft.

[0030] Specifically, the first swinging member is provided with a first through hole which is clearance-matched with the fifth pin shaft.

[0031] Preferably, the lower sports car includes at least two lifting pulley assemblies arranged at intervals, at least two of the lifting pulley assemblies are vertically hinged to the longitudinal beam respectively, the lifting pulley assembly includes a lifting pulley frame and at least two coaxially arranged lifting pulleys arranged on the lifting pulley frame, and all the lifting pulleys on the same lifting pulley frame are rotatably matched with the lifting pulley frame through a second rotating shaft.

[0032] Preferably, the lifting pulley assembly also includes a second swinging member, the second swinging member is arranged corresponding to the longitudinal beam, and the second swinging member and the longitudinal beam are vertically hinged through a fourth pin shaft, the lifting pulley frame is respectively hinged to all the second swinging members on the same lifting pulley assembly, the second swinging member and the lifting pulley frame are hinged through a third pin shaft, and there is an angle between the third pin shaft and the fourth pin shaft.

[0033] During the construction process, the lifting rope (lifting wire rope or lifting wire rope) bypassing the lifting pulley usually has an inclination along the second rotation axis direction, which will apply a bending moment along the second rotation axis direction to the lifting pulley assembly. When the lifting pulley assembly becomes a whole, it will cause the fourth pin to be pulled out axially outward or inward, thereby increasing the probability of damaging the ear plate or the fourth pin that cooperates with the fourth pin. Therefore, a second swinging member is provided as a transition structure between the longitudinal beam and the lifting pulley frame, and the second swinging member is vertically hinged to the longitudinal beam through the fourth pin, and the second swinging member is hinged to the lifting pulley frame through the third pin. There is an angle between the third pin and the fourth pin, which can release the bending moment along the second rotation axis direction within a certain angle range, effectively reducing the probability of damaging the fourth pin, or the first ear plate or the fourth pin that cooperates with the fourth pin.

[0034] Specifically, the third pin axis is perpendicular to the fourth pin axis.

[0035] Specifically, the longitudinal beam is provided with a second through hole which is gap-matched with the fourth pin shaft.

[0036] Specifically, the second swinging member is provided with a second through hole which is clearance-matched with the fourth pin shaft.

[0037] Preferably, a cross bar is provided between at least two of the lifting pulley assemblies vertically hinged to the longitudinal beam, and the cross bar is respectively hinged to the two lifting pulley assemblies through the corresponding second rotating shafts, the second rotating shaft is parallel to the fourth pin shaft, and the cross bar is parallel to the longitudinal beam.

During the climbing or descending of the cable crane sports car on the cable, the whole formed by the two lifting pulley assemblies and the second swing member together with the longitudinal beam and the cross bar constitute an unstable parallelogram structure, so that the shape of the lower sports car can be adaptively changed with the inclination of the cable crane on the cable to adapt to the slope of the cable, so that the cable crane sports car described in the present application can be moved flexibly and conveniently, and the moving range of the cable crane sports car described in the present application on the cable can also be increased.

[0039] Preferably, a flexible structure is provided between the lifting pulley frame and the lifting pulley, and the flexible structure is connected to the lifting pulley frame, so that the flexible structure is attached to the lifting pulley frame around the lifting cable, thereby effectively preventing the lifting cable from scratching the lifting pulley frame.

[0040] Preferably, at least one of the upper sports cars is provided with a first cable support, the first cable support is provided with a first cable support pulley and a second cable support pulley, and the rope groove of the first cable support pulley and the rope groove of the second cable support pulley together form a first matching space for the cable to pass through.

[0041] The above-mentioned cable is the main cable.

[0042] The first cable support is used to control the sag of the main cable, so as to effectively reduce the probability of the main cable and the traction cable becoming entangled with each other due to their closer positions.

[0043] Preferably, at least one of the upper sports car tops is protrudingly provided with a second cable support, the second cable support comprises a cable rack connected to the top of the upper sports car, a third cable pulley and a fourth cable pulley are rotatably connected to the cable rack, and the rope groove of the third cable pulley and the rope groove of the fourth cable pulley together form a second matching space for the rope to pass through.

[0044] When the rope connected to the main rope upper cable support or other ropes need to cross the upper sports car, a second cable support is protrudingly provided on the top of the upper sports car to avoid interference between the rope and the upper sports car.

DETAILED DESCRIPTION

[0060] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0061] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0062] Example 1

[0063] like Figure 1-8 As shown, the present invention implements a cable crane sports car, including an upper sports car 1, a transition frame 4 and a lower sports car 2:

[0064] At least two upper sports cars 1, generally two upper sports cars 1, the upper sports cars 1 comprising at least two pulley block frames 11, a plurality of travel pulleys 12 are coaxially mounted on the pulley block frames 11; all the travel pulleys 12 on the same pulley block frame 11 are mounted on one shaft;

[0065] At least two connecting frames 13 connected between adjacent pulley assembly frames 11, adjacent connecting frames 13 are spaced apart along the axial direction of the walking pulley 12, the connecting frames 13 are hinged to the transition frame 4 through the first pin shaft 3, and all the first pin shafts 3 on the same upper sports car 1 can be coaxially arranged, or misalignment within a certain range can be allowed;

[0066] The transition frame 4 is connected to the lower sports car 2 .

[0067] The first pin 3 is generally located above the cable 8, which is more convenient for installation.

[0068] The sports car of the prior art is to assemble multiple walking pulleys and multiple inverted triangle plates in sequence, and then string them together through pins. However, due to the large number of inverted triangle plates and walking pulleys, the efficiency of stringing the pins one by one is very low, and it is difficult to accurately align them. Based on this, the pulley assembly frame 11 described in the present application is an integral component, such as a welded integral steel component. During assembly, it is only necessary to position the middle hole of the walking pulley to meet the requirements, which saves construction time and improves construction efficiency.

[0069] like Figure 4 and 5 As shown, all the pulley assembly frames 11 and connecting frames 13 on the same upper sports car 1 form an integral component to form a frame structure of the upper sports car 1, which has better overall rigidity and stability, and the installation process is also better and more convenient.

[0070] Specifically, the walking pulley 12 can be a full-length load-bearing wheel.

[0071] When applied to a cable crane, the cable 8 in this embodiment is a main cable.

[0072] On the basis of the above, in a further preferred manner, the first pins 3 on the adjacent upper sports cars 1 are arranged in parallel.

[0073] On the basis of the above, in a further preferred manner, at least two of the upper sports cars 1 are connected only through the transition frame 4. During installation and disassembly, it is only necessary to connect the upper sports car 1 as a whole and the transition frame 4 and the lower sports car 2 as a whole, which greatly reduces the construction workload of installing or disassembling the cable crane sports car on the cable.

[0074] like Figure 1 , 4 As shown in Figure 5, one of the upper sports cars 1 is the first upper sports car 110, and the other of the remaining upper sports cars 1 is the second upper sports car 120. The transition frame 4 includes two longitudinal beams 41 arranged at intervals, and the longitudinal beams 41 are provided with at least two upwardly protruding connecting parts 42, wherein at least one of the connecting parts 42 is hinged to the connecting frame 13 on the first upper sports car 110 through the first pin shaft 3, and at least one of the remaining connecting parts 42 is hinged to the connecting frame 13 on the second upper sports car 120 through the first pin shaft 3, and the adjacent longitudinal beams 41 are fixedly connected.

[0075] The fixed connection in the above solution of this embodiment refers to the adjacent longitudinal beams 41 being relatively fixed by connection, which includes welding or detachable connection, such as bolt connection or riveting.

[0076] like Figure 3 and 8 As shown, the end of the transition frame 4 is hinged with a traction steering wheel assembly 5, which includes a first swinging member 52, a steering wheel frame body 51 and at least two traction sheaves 53 arranged on the steering wheel frame body 51, and the traction sheaves 53 are rotatably matched with the steering wheel frame body 51 through a first rotating shaft 54, wherein at least two of the first rotating shafts 54 are relatively fixed, and at least two of the first rotating shafts 54 are relatively fixed, so that the corresponding traction sheaves 53 are relatively fixed in the direction of the connection line of the two first rotating shafts 54, thereby avoiding collision or friction between the mounting seats of the two traction sheaves 53 when walking on double lines, and effectively ensuring construction safety. The first swinging member 52 is arranged corresponding to the longitudinal beam 41, and the first swinging member 52 and the longitudinal beam 41 are vertically hinged through a fifth pin 56, and all the fifth pins 56 are coaxially arranged, and the steering wheel frame body 51 and each of the first swinging members 52 are hinged through a second pin 55, and there is an angle between the second pin 55 and the fifth pin 56. In general construction, it is best to arrange the second pin shaft 55 and the fifth pin shaft 56 perpendicularly to each other.

[0077] During the construction process, the traction rope (traction wire rope) bypassing the traction pulley 53 usually applies a tilting force along the direction of the fifth pin 56 to the traction steering wheel assembly 5, which will apply a bending moment along the direction of the second rotating shaft 64 to the traction steering wheel assembly 5. When the traction steering wheel assembly 5 becomes an integral unit, the fifth pin 56 will be pulled out axially outward or inward, thereby increasing the probability of damaging the fifth pin 56 or the second ear plate 57 matched with the fifth pin 56. Therefore, the first swing member 52 is provided as a transition structure between the longitudinal beam 41 and the steering wheel frame body 51, the first swing member 52 is hinged to the longitudinal beam 41 through the fifth pin 56, and the steering wheel frame body 51 and each of the first swing members 52 are hinged through the second pin 55, and there is an angle between the second pin 55 and the fifth pin 56. The bending moment along the direction of the fifth pin 56 can be released within a certain angle range, effectively reducing the probability of avoiding damaging the fifth pin 56 or the second ear plate 57 matched with the fifth pin 56.

[0078] Specifically, the longitudinal beam 41 is provided with a first through hole which is clearance-matched with the fifth pin shaft 56 .

[0079] Specifically, the first swinging member 52 is provided with a first through hole which is clearance-matched with the fifth pin shaft 56 .

[0080] Specifically, the second ear plate 57 is located on the first swinging member 52 , and a first through hole that is clearance-matched with the fifth pin shaft 56 is provided on the second ear plate 57 .

[0081] On the basis of the above, a further preferred method is as follows Figure 6 and 7 As shown, the lower sports car 2 includes two lifting pulley assemblies 6 arranged at intervals, and the two lifting pulley assemblies 6 are vertically hinged to the longitudinal beam 41 respectively. The lifting pulley assembly 6 includes a lifting pulley frame 61 and at least two coaxially arranged lifting pulleys 63 arranged on the lifting pulley frame 61. All the lifting pulleys 63 on the same lifting pulley frame 61 are rotatably matched with the lifting pulley frame 61 through a second rotating shaft 64.

[0082] The lifting pulley assembly 6 further includes a second swinging member 62, which is arranged corresponding to the longitudinal beam 41, and the second swinging member 62 and the longitudinal beam 41 are vertically hinged through a fourth pin 66. The lifting pulley frame 61 is hinged to all the second swinging members 62 on the same lifting pulley assembly 6, respectively, and the second swinging member 62 and the lifting pulley frame 61 are hinged through a third pin 65, and there is an angle between the third pin 65 and the fourth pin 66. The third pin 65 and the fourth pin 66 are arranged perpendicular to each other for the best effect.

[0083] During the construction process, the lifting rope (lifting wire rope or lifting wire rope) passing around the lifting pulley 63 usually has an inclination along the second rotation axis 64, which will apply a bending moment along the second rotation axis 64 to the lifting pulley assembly 6. When the lifting pulley assembly 6 becomes a whole, it will cause the fourth pin 66 to be pulled out axially outward or inward, thereby increasing the probability of damaging the ear plate or the fourth pin 66 that matches the fourth pin 66. Therefore, the second swinging member 62 is provided as a connection between the longitudinal beam 41 and the lifting The transition structure between the pulley frame 61, the second swing member 62 and the longitudinal beam 41 are vertically hinged through the fourth pin 66, the second swing member 62 and the lifting pulley frame 61 are hinged through the third pin 65, and there is an angle between the third pin 65 and the fourth pin 66, which can release the bending moment along the second rotating axis 64 within a certain angle range, effectively reducing the probability of damaging the fourth pin 66, or the first ear plate 67 or the fourth pin 66 matched with the fourth pin 66.

[0084] Specifically, the longitudinal beam 41 is provided with a second through hole which is clearance-matched with the fourth pin shaft 66 .

[0085] Specifically, the second swinging member 62 is provided with a second through hole which is clearance-matched with the fourth pin shaft 66 .

[0086] Specifically, the first ear plate 67 is located on the second swinging member 62 , and a second through hole that is clearance-matched with the fourth pin shaft 66 is provided on the first ear plate 67 .

[0087] On the basis of the above, a further preferred method is that a cross bar 7 is arranged between at least two of the lifting pulley assemblies 6 vertically hinged to the longitudinal beam 41, and the cross bar 7 is respectively hinged to the two lifting pulley assemblies 6 through the corresponding second rotating shaft 64, the second rotating shaft 64 is parallel to the fourth pin shaft 66, and the cross bar 7 is parallel to the longitudinal beam 41. A cable crane sports car described in the present application is provided with a cross bar 7 between the two lifting pulley assemblies 6, the cross bar 7 is respectively hinged to the two lifting pulley assemblies 6, the lifting pulley assembly 6 is hinged to the longitudinal beam 41 through the second swing member 62, and the cross bar 7 is parallel to the longitudinal beam 41. When the cable crane sports car climbs or descends on the cable 8, the whole formed by the two lifting pulley assemblies 6 and the second swing member 62 together with the longitudinal beam 41 and the cross bar 7 constitute an unstable parallelogram structure, so that the shape of the lower sports car 2 can be adaptively changed with the inclination of the cable 8 crane on the cable 8 to adapt to the slope of the cable 8, so that the cable crane sports car described in the present application can be moved flexibly and conveniently, and the moving range of the cable crane sports car described in the present application on the cable 8 can also be increased.

[0089] The first cable support 9 is used to control the sag of the main cable, so as to effectively reduce the probability of the main cable and the traction cable being entangled with each other due to their closer positions.

[0090] On the basis of the above, a further preferred method is as follows Figure 9-12 As shown, at least one of the upper sports car 1 has a second cable support 10 protruding from the top, the second cable support 10 includes a cable rack 101 connected to the top of the upper sports car 1, a third cable pulley 102 and a fourth cable pulley 103 are rotatably connected to the cable rack 101, and the rope groove of the third cable pulley 102 and the rope groove of the fourth cable pulley 103 together form a second matching space 105 for the rope 104 to pass through.

[0091] When the rope 104 connected to the main rope upper cable holder or other ropes 104 need to cross the upper sports car 1, a second cable holder 10 is protrudingly provided on the top of the upper sports car 1 to prevent the rope 104 from interfering with the upper sports car 1.

[0092] Beneficial effects of this embodiment:

[0093] 1. A cable crane sports car described in this embodiment has at least two pulley block frames 11, and a plurality of walking pulleys 12 are installed on the pulley block frames 11; the plurality of walking pulleys 12 installed on the pulley block frames 11, all the walking pulleys 12 on the same pulley block frame 11 are coaxially arranged, so that the upper sports car 1 can move in coordination with the cable 8 on the cable 8, and at least two connecting frames 13 are arranged between adjacent pulley block frames 11, and are connected to the transition frame 4 through the connecting frames 13, so as to achieve the lower sports car 2 and the upper For the purpose of connecting the upper sports car 1, there are at least two connecting frames 13, the connecting frames 13 and the transition frame 4 are hinged through the first pin shaft 3, and all the first pin shafts 3 on the same upper sports car 1 are coaxially arranged. Compared with the existing through-axis pin shaft, the cable crane sports car described in the present application has an upper sports car 1 and a transition frame 4 hinged through at least two first pin shafts 3, which effectively reduces the unit length of the connecting pin shaft between the upper sports car 1 and the lower sports car 2, thereby effectively reducing the difficulty of installing and disassembling the cable crane sports car.

[0094] 2. The conventional cable crane sports car includes a load-bearing bracket and a lifting bracket, wherein the load-bearing bracket includes a plurality of inverted triangular load-bearing frames arranged side by side, and the lateral movement of the cable 8 is limited by the load-bearing frames. Since the load-bearing frames are located at both ends of the pulley, the lateral displacement of the cable 8 is relatively large. Based on this, by providing ribs on the walking pulley 12 (changing the wheel groove depth) and by making the pulley assembly frame 11 integrally increased, the overall weight of the upper sports car 1 or the cable crane sports car is effectively limited in the lateral movement of the cable 8.

[0095] 3. During the installation process of the traditional sports car, it is necessary to install the load-bearing wheels, load-bearing frame plates (inverted triangle plates), load-bearing shafts and other components one by one. Due to the large number of load-bearing frames and load-bearing wheels, and the load-bearing shafts need to run through all the load-bearing wheels and load-bearing frames, the load-bearing shafts and the load-bearing wheels and the load-bearing frame plates need to be accurately aligned, resulting in a series of problems such as low construction efficiency and great construction difficulty. Based on this, the cable crane sports car described in this application is improved as follows: the load-bearing frame plates are cancelled, and the traditional multiple single load-bearing wheels can be changed to full-length load-bearing wheels to avoid the problems of difficulty in aligning the load-bearing long axis due to multiple holes and long distances. In addition, the traditional full-length axis connected to the lower sports car is further changed into several first pins 3 to fix the whole formed by the lower sports car 2 and the transition frame 4 to the upper sports car 1, which greatly reduces the length of a single full-length axis. This construction method also greatly reduces the construction workload of the cable crane sports car disassembly.

[0096] 4. Since the cable crane sports car will walk along a certain slope on the main cable, the lifting cable and the surrounding steel plates are easily scratched. A flexible structure is provided between the lifting pulley frame 61 and the lifting pulley 63 described in the present application, and the flexible structure is connected to the lifting pulley frame 61. The steel plate on the lifting pulley frame 61 around the lifting cable is pasted with a flexible structure, generally a rubber plate or a plastic plate, which effectively prevents the lifting cable from scratching the steel plate. In addition, a second cable support 10 is added to the upper part of the upper sports car 1 for the connection rope connected to the cable support on the main cable to pass through.

[0097] 5. The cable crane sports car of this embodiment provides a safer and more flexible sports car traction device, which integrates the existing traction pulley group to avoid collision between adjacent traction pulley groups during the operation of the sports car. Traditionally, only multiple sets of lines can be used. When the hoisting load is small, the two traction pulley groups will produce greater collision and friction when running double lines, resulting in a series of problems such as large material loss and poor construction safety. Based on this, the cable crane sports car of this embodiment improves the structure, and fixes the relative positions of adjacent traction pulleys 53 by steel plates to avoid collision between adjacent traction pulleys 53 when running double lines.

[0098] 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 in the protection scope of the present invention.
