Description

Technical Field

[0001] The present invention relates to a sanitation equipment, in particular to an automatic control lifting device and a garbage compressor using the automatic control lifting device. Background Art

[0002] The lifting devices of traditional garbage compressors mostly adopt a structural form integrally welded on the box body, which is difficult to disassemble, install and replace. Moreover, the pull ring serving as the lifting device interferes with the flipping of the garbage hopper. To avoid this interference phenomenon, some garbage compressors have taken the measure of actively reducing the size of the pull ring, but this will lead to the problem of inconvenient docking with the hook-arm vehicle. There is also a flip-type garbage compressor lifting device on the market. By rotatably arranging the pull ring, the fixation of the pull ring mainly relies on manual operation. Since the overall weight of the pull ring is relatively heavy, the labor intensity of the staff is large and there are serious safety hazards. Especially when lifting operations are required, the staff need to hold the relatively heavy pull ring by hand and insert a bolt to fix it after reaching the set position. It is easy to cause accidents of hitting by dropping the hand during the process of holding by hand. When the staff perform the fixing work alone, it will further increase the installation difficulty of the bolt and the safety hazards. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason:

[0004] On the one hand, the present invention provides an automatic control lifting device, which realizes the lifting and fixing of the lifting part through an automatic control mechanism, so as to reduce the labor intensity of the staff and eliminate safety hazards.

[0005] The automatic control lifting device according to the first aspect embodiment of the present invention includes:

[0006] A fixing member;

[0007] A rotating member rotatably arranged on the fixing member, and a plurality of positioning holes are arranged around the rotation center of the rotating member;

[0008] An automatic control mechanism rotatably installed on the fixing member, and the axis of its rotating shaft does not coincide with the axis of the rotating member. The automatic control mechanism has a first control part and a second control part. The first control part is rotationally connected to the rotating member and is used to control the rotation of the rotating member. The second control part is used to be inserted into the positioning hole and lock the fixing member and the rotating member after the rotating member rotates a set angle.

[0009] The automatic control lifting device according to the embodiment of the present invention has at least the following technical effects:

[0010] The automated control lifting device proposed by the present invention uses a rotating member for lifting operations. The rotating member is rotatably connected to the fixed member, which not only provides a convenient disassembly and assembly method but also avoids interference with other components by rotating the rotating member. Specifically, since the rotation axes of the rotating member and the automated control mechanism do not coincide, a link structure is formed after the rotating member is rotatably connected by the first control part. When the length of the first control part changes, it can drive the rotating member to rotate. In this way, through the cooperation of the first control part and the second control part, the automated control function can be exerted, thus replacing manual operation to complete the rotation and fixation of the rotating member. This not only reduces the labor intensity of the staff but also eliminates the safety hazards existing in manual operation.

[0011] According to some embodiments of the present invention, the first control part is provided with a telescopic end connecting the rotating member and a fixed end communicating with the second control part. The second control part is provided with a telescopic end rotatably connected to the fixed member. The automated control mechanism controls the telescopic movement of the first control part to drive the rotating member to rotate, so that the positioning hole is aligned with the telescopic end of the second control part during the rotation. In this way, when the rotating member rotates by a set angle, the telescopic end of the second control part is inserted into the positioning hole and locked, and the fixation between the rotating member and the fixed member can be realized, thereby realizing fixed installation and facilitating the lifting work.

[0012] According to some embodiments of the present invention, the first control part is provided with a first cylinder body and a first piston rod disposed in the rodless cavity of the first cylinder body. The second control part is provided with a second cylinder body, a third cylinder body communicating with the second cylinder body, a second piston rod disposed in the rodless cavity of the second cylinder body, and a third piston rod disposed in the rodless cavity of the third cylinder body. A three-cylinder control structure is formed by the combined structure of the first cylinder body, the second cylinder body, and the third cylinder body. Correspondingly, the first cylinder body corresponds to the fixed end of the first control part, the first piston rod is connected to the rotating member and corresponds to the telescopic end of the first control part. The second cylinder body and the third cylinder body correspond to the fixed end of the second control part, and the second piston rod and the third piston rod correspond to the telescopic end of the second control part. When the second piston rod and the third piston rod extend and are inserted into the positioning hole, the connection between the rotating member and the fixed member can be realized.

[0013] According to some embodiments of the present invention, one ends of the first cylinder block, the second cylinder block, and the third cylinder block are interconnected to form a three-way cylinder base. The three-way cylinder base is provided with a second interface, and a first one-way valve leading outward is arranged in the second interface. A movable valve rod is arranged at an end of the first piston rod located in the first cylinder block. The movable valve rod opens and closes the second interface within a moving stroke range when moving along with the first piston rod. Combining the above structure, the linkage principle of the first piston rod, the second piston rod, and the third piston rod can be obtained. That is, when the first piston rod moves towards the three-way cylinder base, before the movable valve rod abuts against the second interface, the first one-way valve continuously conducts the second interface to enable the first piston rod to move stably. After the movable valve rod abuts against the second interface and closes it, the thrust of the hydraulic oil starts to act in the other two directions via the three-way cylinder base, causing the second piston rod and the third piston rod to extend and connect to the positioning holes, thereby realizing the fixation of the rotating member.

[0014] According to some embodiments of the present invention, a first interface is arranged on the first cylinder block, and a first overflow branch is arranged at a position of the first piston rod close to the movable valve rod for opening and closing the first interface. Obviously, the first interface here is mainly used for oil inlet, and the first overflow branch is mainly used for allowing the oil inlet to enter the three-way cylinder base through the first overflow branch to drive the second piston rod and the third piston rod to move after the movable valve rod abuts against the second interface and closes it.

[0015] According to some embodiments of the present invention, a return spring and a frustum-shaped core head are respectively arranged at two ends of the movable valve rod. One end of the return spring is connected to the movable valve rod, and the other end is connected to the end of the first piston rod. The maximum cross-sectional area of the core head is larger than the minimum cross-sectional area of the second interface, so that the second interface can be fully closed when the movable valve rod abuts against the second interface.

[0016] According to some embodiments of the present invention, a third interface and a fourth interface are sequentially arranged on the second cylinder block along the extending direction of the second piston rod. A second one-way valve leading outward is arranged in the fourth interface. A second overflow branch is arranged at a position of the second piston rod close to the fourth interface. Obviously, the fourth interface here is the oil outlet, the third interface is the oil inlet, and the second overflow branch is mainly used for pressure relief from the side of the third interface to the side of the fourth interface and pushing the first piston rod while relieving the pressure.

[0017] According to some embodiments of the present invention, a fifth interface and a sixth interface are sequentially arranged on the third cylinder block along the extending direction of the third piston rod. A third one-way valve communicating outward is arranged in the fifth interface. The third piston rod is provided with a third overflow branch near the fifth interface. Similarly, the fifth interface here is an oil outlet, and the sixth interface is an oil inlet. The third overflow branch is mainly used for relieving pressure from the side of the sixth interface to the side of the fifth interface and pushing the first piston rod while relieving pressure.

[0018] According to some embodiments of the present invention, the first overflow branch, the second overflow branch, and the third overflow branch have the same circuit structure, that is, they are all provided with an overflow channel connecting the rod chamber and the rodless chamber of the cylinder block (including the first cylinder block, the second cylinder block, and the third cylinder block), and a reset valve core arranged in the overflow channel. The reset valve core can open the overflow channel under the action of oil pressure to relieve pressure and perform the overflow function of the overflow valve.

[0019] According to some embodiments of the present invention, a suitable mechanical locking structure is arranged on the circuit structure to improve the reliability of the circuit structure.

[0020] On the other hand, the present invention also proposes a garbage compressor provided with the above-mentioned automatic control lifting device. By using the automatic control lifting device to complete the fixing work of the pull ring, the hoisting and transportation work of the garbage compressor can be completed safely and efficiently.

[0021] The garbage compressor according to the second aspect embodiment of the present invention includes a box body, and the above-mentioned automatic control lifting device is arranged at the upper part of the front end of the box body.

[0022] The garbage compressor according to the embodiments of the present invention has at least the following technical effects:

[0023] For the garbage compressor proposed by the present invention, an automatic control lifting device is arranged at the upper part of the front end of the box body, which can realize the automatic control of the rotation of the pull ring of the lifting device and the fixing at a set position (the position for hoisting), thereby facilitating the hoisting work, reducing the labor intensity of the staff, and eliminating the potential safety hazards existing in manual operation.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0037] Referring to Figures 1 to 5 , on the one hand, the present invention provides an automated control hoisting device, which realizes the lifting and fixing of the hoisting device through an automated control mechanism, so as to reduce the labor intensity of workers and eliminate potential safety hazards.

[0038] As Figure 1 , Figure 2 and Figure 3 shown, the automated control hoisting device proposed by the present invention includes:

[0039] A fixing member;

[0040] A rotating member rotatably arranged on the fixing member, and a plurality of positioning holes are arranged around the rotation center of the rotating member;

[0041] An automated control mechanism rotatably installed on the fixing member, the axis of which is not coincident with the axis of the rotating member. The automated control mechanism has a first control part and a second control part. The first control part is rotatably connected to the rotating member for controlling the rotation of the rotating member, and the second control part is used for engaging into the positioning hole and locking the fixing member and the rotating member after the rotating member rotates a set angle.

[0042] According to the above structure, for the automated control hoisting device proposed by the present invention, the rotating member is used for hoisting operations, a pull ring is arranged on the rotating member, and the rotating member and the fixing member are rotatably connected. This installation method can not only provide a convenient disassembly and assembly method, but also avoid interference between the pull ring and other components by rotating the rotating member. Specifically, since the axis of the rotating member and the axis of the automated control mechanism do not coincide, a link structure is formed after the first control part is rotatably connected to the rotating member. When the length of the first control part changes, the rotating member can be driven to rotate. In this way, the automated control function can be realized through the cooperation of the first control part and the second control part, so as to replace manual operation to complete the rotation and fixing of the rotating member. This can not only reduce the labor intensity of workers, but also eliminate potential safety hazards existing in manual operation.

[0043] According to some embodiments of the present invention, such as Figure 1 , Figure 2 and Figure 3As shown in the figure, the first control part is provided with a telescopic end connected to the rotating part and a fixed end communicating with the second control part. The second control part is provided with a telescopic end rotatably connected to the fixed part. The automatic control mechanism controls the telescoping of the first control part to drive the rotating part to rotate, so that the positioning hole is aligned with the telescopic end of the second control part during the rotation. In this way, when the pull ring rotates by a set angle with the rotating part, the telescopic end of the second control part is inserted into the positioning hole and locked, so as to fix the rotating part and the fixed part, and further realize the fixed installation of the pull ring, thus facilitating the hoisting work.

[0044] According to some embodiments of the present invention, as Figure 4 shown in the figure, the first control part is provided with a first cylinder body 200 and a first piston rod 201 disposed in the rodless cavity of the first cylinder body 200. The second control part is provided with a second cylinder body 300, a third cylinder body 400 communicating with the second cylinder body 300, a second piston rod 202 disposed in the rodless cavity of the second cylinder body 300, and a third piston rod 203 disposed in the rodless cavity of the third cylinder body 400. A three-cylinder control structure is formed by the combined structure of the first cylinder body 200, the second cylinder body 300, and the third cylinder body 400. Correspondingly, the first cylinder body 200 corresponds to the fixed end of the first control part, the first piston rod 201 is connected to the rotating part, corresponding to the telescopic end of the first control part. The second cylinder body 300 and the third cylinder body 400 correspond to the fixed end of the second control part, and the second piston rod 202 and the third piston rod 203 correspond to the telescopic end of the second control part. When the second piston rod 202 and the third piston rod 203 extend to be inserted into the positioning hole, the connection between the rotating part and the fixed part can be realized. Further, obviously, the second piston rod 202 and the third piston rod 203 play a plugging role similar to that of a bolt here.

[0045] According to some embodiments of the present invention, as Figure 4 shown in the figure, one ends of the first cylinder body 200, the second cylinder body 300, and the third cylinder body 400 are interconnected to form a three-way cylinder seat. The three-way cylinder seat is provided with a second interface 207. A first one-way valve leading outward is disposed in the second interface 207. A moving valve stem 206 is disposed at the end of the first piston rod 201 located in the first cylinder body 200. The moving valve stem 206 opens and closes the second interface 207 within the moving stroke range of moving with the first piston rod 201. Combining the above structure, the linkage principle of the first piston rod 201, the second piston rod 202, and the third piston rod 203 can be obtained, that is, when the first piston rod 201 moves towards the three-way cylinder seat, before the moving valve stem 206 abuts against the second interface 207, the first one-way valve continuously conducts the second interface 207 to enable the first piston rod 201 to move stably. After the moving valve stem 206 abuts against the second interface 207 to close it, the thrust of the hydraulic oil starts to act in the other two directions via the three-way cylinder seat, causing the second piston rod 202 and the third piston rod 203 to extend and connect to the positioning hole, thereby realizing the fixation of the rotating part.

[0046] According to some embodiments of the present invention, as Figure 4 shown, the three-way cylinder seat is a T-shaped cylinder structure for easy installation.

[0047] According to some embodiments of the present invention, as Figure 4 、 Figure 5 shown, a first interface is provided on the first cylinder block 200, and a first overflow branch is provided on the first piston rod 201 near the position of the movable valve rod 206 for opening and closing the first interface. Obviously, the first interface here is mainly used for oil inlet, and the first overflow branch is mainly used for driving the second piston rod 209 and the third piston rod 203 to move after the movable valve rod 206 abuts against the second interface 207 to close it, so that the oil inlet enters the three-way cylinder seat through the first overflow branch. In this way, while realizing the oil pressure relief at the first inlet end, the extension control of the second piston rod 202 and the third piston rod 203 can be completed.

[0048] According to some embodiments of the present invention, as Figure 4 shown, a return spring and a frustum-shaped core head are respectively provided at both ends of the movable valve rod 206. One end of the return spring is connected to the movable valve rod 206, and the other end is connected to the end of the first piston rod 201. The maximum cross-sectional area of the core head is larger than the minimum cross-sectional area of the second interface 207, so that the second interface 207 can be fully closed when the movable valve rod 206 abuts against the second interface 207.

[0049] According to some embodiments of the present invention, as Figure 4 、 Figure 5 shown, a third interface and a fourth interface are sequentially provided on the second cylinder block 300 along the extending direction of the second piston rod 202. A second one-way valve leading outward is provided in the fourth interface, and a second overflow branch is provided on the second piston rod 202 near the position of the fourth interface. Obviously, the fourth interface here is the oil outlet, the third interface is the oil inlet, and the second overflow branch is mainly used for pressure relief from the third interface side to the fourth interface side, and at the same time pushes the first piston rod 201 when pressure relief is carried out. Obviously, in combination with the figure, the pressure relief state here means that the second piston rod 202 has been retracted into the set position in the second cylinder block 300, that is, after exactly blocking the fourth interface, continuous oil inlet at the third interface will cause the oil pressure to increase, and pressure relief needs to be carried out through the second overflow branch and the first piston rod 201 is pushed to extend.

[0050] According to some embodiments of the present invention, as Figure 4 、 Figure 5As shown, a fifth interface and a sixth interface are successively arranged on the third cylinder block 400 along the extending direction of the third piston rod 203. A third one-way valve communicating outward is arranged in the fifth interface. The third piston rod 203 is provided with a third overflow branch near the fifth interface. Similarly, similar to the setting relationship and working principle between the second piston rod 202 and the second cylinder block 300 above, the fifth interface here is the oil outlet, the sixth interface is the oil inlet, and the third overflow branch is mainly used for pressure relief from the sixth interface side to the fifth interface side, and while pressure relief is carried out, it pushes the first piston rod 201.

[0051] According to some embodiments of the present invention, as Figure 4 , Figure 5 shown, the first overflow branch, the second overflow branch, and the third overflow branch have the same loop structure, that is, both are provided with a rodless cavity and a rod cavity overflow channel 208 communicating with the cylinder blocks (including the first cylinder block 200, the second cylinder block 300, and the third cylinder block 400), and a return valve core 204 arranged in the overflow channel 208. The return valve core 204 can open the overflow channel 208 under the action of oil pressure to achieve pressure relief and play the overflow function of the overflow valve.

[0052] According to some embodiments of the present invention, in order to improve the working stability of the moving valve stem 206 and the first overflow branch, as Figure 4 shown, the first piston rod 201 is provided with a valve seat covering the overflow channel 208 at the position where the moving valve stem 206 is installed. The valve seat has a cavity and is provided with an overflow hole communicating with the cavity and the overflow channel 208 at the end near the first piston rod 201. A fitting valve block is arranged in the valve seat. One end of the return spring is connected to the valve block, and the other end is connected to the first piston rod 201. One end of the moving valve stem 206 is connected to the valve block, and the other end provided with a frustum-shaped core head extends out of the valve seat. Under the action of the oil pressure of the hydraulic oil flowing out through the overflow channel 208, the valve block moves downward in the valve seat and drives the moving valve stem 206 towards the second interface 207. When the overflow hole is opened during movement, the first overflow branch starts to play the overflow function. On the contrary, when overflow is not required, the moving valve stem 206 is reset under the action of the return spring to close the overflow hole and the overflow channel 208, and cooperating with the return valve core 204 in the overflow channel 208 can further ensure the working stability of the first overflow branch.

[0053] According to some embodiments of the present invention, as Figure 4 shown, a fitting mechanical locking structure 205 is arranged on the loop structure to be used for improving the reliability of the loop structure.

[0054] According to some embodiments of the present invention, as Figure 4As shown in the figure, the mechanical locking structure 205 is a mechanical lock used in a conventional hydraulic cylinder, which mainly includes a spring piece, a conical surface and a steel ball. Among them, the spring piece has a certain radian, and the spring piece interacts with the conical surface along the protruding direction of the radian to hold the steel ball against the inner wall of the cylinder barrel of the corresponding hydraulic cylinder, so that the hydraulic cylinder can be locked in any position.

[0055] In summary, the automatic control mechanism is essentially a three-cylinder control structure. For the linkage control between the three-cylinder control structures and the sequential realization of the rotation and fixation (relaxation) of the rotating member, in addition to the second control part being symmetrically arranged left and right in terms of structure, the oil inlet states of the third interface and the fifth interface here also preferably remain the same. At the same time, the rotation center of the second control part is located above the rotation center of the rotating member. Only in this way can it be ensured that when the rotating member needs to be relaxed, the second piston rod 202 and the third piston rod 203 are retracted to the set positions in the corresponding cylinders without interfering with the rotation of the rotating member, and at the same time, the first piston rod 201 starts to extend smoothly, driving the rotating member to turn downward to the set position within the rotation range (a position that will not interfere with other components); and when the rotating member needs to be rotationally fixed, after the first piston rod 201 is smoothly retracted and drives the rotating member to turn upward to the set position for hoisting, the second piston rod 202 and the third piston rod 203 extend smoothly and are inserted into the positioning holes of the rotating member to fix the rotating member.

[0056] On the other hand, as Figure 1 shown, the present invention also proposes a garbage compressor provided with the above automatic control hoisting device. By using the automatic control hoisting device to complete the fixing work of the pull ring, the hoisting and transfer work of the garbage compressor can be completed safely and efficiently.

[0057] Referring to Figure 1 , the garbage compressor proposed by the present invention includes a box body 100, and the above automatic control hoisting device is arranged on the upper part of the front end of the box body 100.

[0058] According to the above structure, the garbage compressor proposed by the present invention is provided with an automatic control hoisting device on the upper part of the front end of the box body 100, which can realize the automatic control of the rotation of the pull ring and the fixation at the set position (the position for hoisting), thereby facilitating the hoisting work, reducing the labor intensity of the staff, and eliminating the safety hazards existing in manual operation.

[0059] In summary, in combination with Figures 1 to 5 , the specific structure and installation method of the automatic control hoisting device will be further described here:

[0060] The fixing member is provided with two fixing plates 101 symmetrically arranged at the front part of the upper end of the box body 100. Each fixing plate 101 is formed by splicing two steel plates, and there is a gap between the two steel plates. The rotating member is provided with two pull-ring ear plates 105 adaptively installed in the above-mentioned gap. The fixing plate 101 is provided with a rotating hole 102 and a plugging hole 103 at appropriate positions. The pull-ring ear plate 105 is provided with a positioning hole corresponding to the plugging hole 103, so that when hoisting operations are required, after the pull-ring ear plate 105 is rotated to a set position by the automatic control mechanism, the positioning hole is directly opposite to the plugging hole 103, facilitating the second piston rod 202 and the third piston rod 203 to extend into and be connected and fixed. Further, one end of the two pull-ring ear plates 105 is connected through a suitable round nut 108 and a connecting pin 109 passing through the rotating hole 102 to achieve rotational installation on the fixing plate 101, and the other end is connected with a pull ring 107 for hoisting. At an appropriate position away from the pull ring 107, a connecting rod 106 is passed through between the two pull-ring ear plates 105. The automatic control mechanism is set as a three-cylinder linkage hydraulic cylinder, whose first piston rod 201 is rotationally connected to the connecting rod 106. When the second piston rod 202 and the third piston rod 203 can rotate freely, the second piston rod 202 and the third piston rod 203 only extend into the plugging hole 103 of the adjacent steel plate (as shown in Figure 3 ), and when it is necessary to fix the pull-ring ear plate 105 and the pull ring 107, they are further moved to pass through the plugging holes 103 of the adjacent two steel plates (as shown in Figure 2 ). In this way, both the rotational installation of the automatic control mechanism can be realized and the fixing function can be exerted when necessary.

[0061] According to some embodiments of the present invention, in order to improve the bearing capacity and rotational ability of the second piston rod 202 and the third piston rod 203 in the plugging hole 103, a suitable bushing 104 is arranged in the plugging hole 103.
