Description

Technical Field

[0001] This utility model relates to the field of crane technology, and more specifically, to a lightweight trolley for a general-purpose gantry crane. Background Technology

[0002] The trolley is a part of a bridge crane. The trolley moves laterally along the rails laid on the bridge, making full use of the space under the bridge to lift materials without being obstructed by ground equipment. It is widely used in indoor and outdoor warehouses, factories, docks and open storage yards.

[0003] The lightweight crane trolleys currently in use bear a large weight, which may cause some deformation of the trolley frame. This can lead to a certain angular displacement of the four wheels, resulting in three wheels supporting the trolley's movement. This distributes the entire weight onto the three wheels, causing them to bear greater force and potentially damaging them. This can render the trolley unusable and require repair, ultimately reducing production efficiency. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a lightweight trolley for a universal gantry crane, which has the advantages of individually installing the four wheels of the trolley and improving the support capacity of the wheels.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lightweight trolley for a general-purpose gantry crane, comprising a frame, wherein two frames are provided, and a base plate is fixedly connected between the two frames. A lifting device is fixedly connected to the top of the base plate. A support assembly is provided on the outside of the frame, the support assembly including a first rotating seat fixedly connected to the outside of the frame, a first connecting ring rotatably connected inside the first rotating seat, a sleeve fixedly connected to the bottom of the first connecting ring, a first sliding rod slidably connected inside the sleeve, a fixed plate fixedly connected to the outside of both the sleeve and the first sliding rod, a spring fixedly connected between the two fixed plates, and a second rotating seat fixedly connected to the bottom of the first sliding rod.

[0006] As a preferred technical solution of this utility model, a positioning component is provided on the outer side of the frame. The positioning component includes two first upright plates fixedly connected to the outer side of the frame. A third rotating shaft is fixedly connected between the two first upright plates. A second connecting ring is rotatably connected to the outer side of the third rotating shaft. A connecting rod is fixedly connected to the outer side of the second connecting ring. The outer side of the connecting rod is rotatably connected to the inside of the second rotating seat.

[0007] As a preferred embodiment of this utility model, a movable component is provided on the outer side of the connecting rod. The movable component includes a motor fixedly connected to the end of the connecting rod, a transmission rod fixedly connected to the transmission end of the motor, and a mounting plate fixedly connected to the outer side of the transmission rod. Two mounting plates are provided, and the second mounting plate is slidably connected to the outer side of the transmission rod.

[0008] As a preferred embodiment of this utility model, the movable component further includes a wheel movably connected to the outside of the transmission rod. The wheel is disposed between two mounting discs, and the mounting discs are movably connected to the inside of the wheel by bolts. A nut is threaded onto the outside of the bolts.

[0009] As a preferred embodiment of this utility model, a fixing component is provided on the outer side of the connecting rod. The fixing component includes a support frame fixedly connected to the outer side of the connecting rod, and a support rod is fixedly connected to the outer side of the support frame. The end of the support rod is slidably connected to the outer side of the mounting plate.

[0010] As a preferred embodiment of the present invention, an auxiliary component is provided on the outside of the support frame. The auxiliary component includes two second sliding rods fixedly connected to the end of the support frame. A sleeve is slidably connected to the outside of the second sliding rods, and a support arm is fixedly connected to the end of the sleeve.

[0011] As a preferred technical solution of this utility model, the auxiliary component further includes a first rotating shaft rotatably connected inside the support arm, with a second upright plate fixedly connected to each end of the first rotating shaft, the outer side of the second upright plate being fixedly connected to the outer side of the vehicle frame, and a second rotating shaft fixedly connected inside one of the support arms, the second rotating shaft passing through the first slide rod and rotatably connected to the first slide rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model transmits the pressure borne by the frame to the first rotating seat, thereby transmitting power to the first connecting ring, then to the sleeve, and finally to the fixed plate. This causes the sleeve to slide outside the first sliding rod, compressing the spring, and then transmitting the pressure to the second rotating seat. This distributes the pressure. Through the cooperation of the first sliding rod, sleeve, fixed plate, and spring, the sleeve and first sliding rod can adjust their lengths under the action of the spring when the frame deforms. This ensures that the wheels can always contact the crane, reducing the possibility of three wheels bearing all the weight, thus reducing the possibility of wheel overload and damage, reducing potential maintenance time, and improving production efficiency.

[0014] 2. This utility model uses a second sliding rod to restrict the position of the sleeve, thereby supporting the support arm. Subsequently, the position of the support arm can be restricted by the second vertical plate and the first rotating shaft. The second rotating shaft can connect one of the support arms to the first sliding rod, thereby transmitting the pressure on the first sliding rod to the support arm, thus improving the support. It also allows the wheels to move up and down within a certain range, so that the wheels can always be in contact with the lifting frame. This further reduces the possibility of three wheels bearing all the weight, thereby reducing the possibility of the wheels being overloaded and damaged. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 6As shown, this utility model provides a lightweight trolley for a universal gantry crane, including a frame 1. Two frames 1 are provided, and a base plate 2 is fixedly connected between the two frames 1. A lifting device 26 is fixedly connected to the top of the base plate 2. A support assembly is provided on the outside of the frame 1. The support assembly includes a first rotating seat 3 fixedly connected to the outside of the frame 1. A first connecting ring 4 is rotatably connected inside the first rotating seat 3. A sleeve 5 is fixedly connected to the bottom of the first connecting ring 4. A first sliding rod 6 is slidably connected inside the sleeve 5. Fixed plates 7 are fixedly connected to the outside of both the sleeve 5 and the first sliding rod 6. A spring 8 is fixedly connected between the two fixed plates 7. A second rotating seat 27 is fixedly connected to the bottom of the first sliding rod 6.

[0024] The pressure borne by the frame 1 is transmitted to the first rotating seat 3, thereby transmitting power to the first connecting ring 4, then to the sleeve 5, and finally to the fixed plate 7. This causes the sleeve 5 to slide outside the first sliding rod 6, compressing the spring 8, and then transmitting the pressure to the second rotating seat 27. This distributes the pressure. Through the cooperation of the first sliding rod 6, sleeve 5, fixed plate 7, and spring 8, when the frame 1 deforms, the sleeve 5 and the first sliding rod 6 can adjust their length under the action of the spring 8. This ensures that the wheels 15 can always contact the crane, reducing the possibility of all three wheels 15 bearing the entire weight, thus reducing the possibility of overloading the wheels 15 and causing damage, reducing potential maintenance time, and improving production efficiency.

[0025] The frame 1 is provided with a positioning component on its outer side. The positioning component includes two first upright plates 9 fixedly connected to the outer side of the frame 1. A third rotating shaft is fixedly connected between the two first upright plates 9. A second connecting ring 10 is rotatably connected to the outer side of the third rotating shaft. A connecting rod 11 is fixedly connected to the outer side of the second connecting ring 10. The outer side of the connecting rod 11 is rotatably connected to the inside of the second rotating seat 27.

[0026] The position of the second connecting ring 10 is restricted by the first upright plate 9, thereby restricting the position of the connecting rod 11, and the position of the connecting rod 11 is further restricted by the second rotating seat 27.

[0027] The connecting rod 11 has a movable component on its outer side. The movable component includes a motor 12 fixedly connected to the end of the connecting rod 11. The transmission end of the motor 12 is fixedly connected to a transmission rod 13. The transmission rod 13 is fixedly connected to a mounting plate 14 on its outer side. There are two mounting plates 14. The second mounting plate 14 is slidably connected to the outer side of the transmission rod 13.

[0028] The motor 12 drives the transmission rod 13 to rotate, which in turn drives the mounting plate 14 to rotate.

[0029] The movable component also includes a wheel 15 movably connected to the outside of the transmission rod 13. The wheel 15 is disposed between two mounting plates 14. The mounting plates 14 and the wheel 15 are movably connected by bolts 16, and the bolts 16 are threaded with nuts 17 on the outside.

[0030] The rotation of the mounting plate 14 drives the rotation of the wheel 15, thereby moving the entire device.

[0031] The connecting rod 11 is provided with a fixing component on its outer side. The fixing component includes a support frame 18 fixedly connected to the outer side of the connecting rod 11. A support rod 19 is fixedly connected to the outer side of the support frame 18. The end of the support rod 19 is slidably connected to the outer side of the mounting plate 14.

[0032] The position of the support rod 19 is restricted by the support frame 18, thereby restricting the position of the mounting plate 14.

[0033] The support frame 18 is provided with an auxiliary component on its outer side. The auxiliary component includes two second slide rods 20 fixedly connected to the end of the support frame 18. A sleeve 21 is slidably connected to the outer side of the second slide rods 20, and a support arm 22 is fixedly connected to the end of the sleeve 21.

[0034] The second slide bar 20 restricts the position of the sleeve 21, thereby supporting the support arm 22.

[0035] The auxiliary components also include a first rotating shaft 23 rotatably connected inside the support arm 22. The two ends of the first rotating shaft 23 are respectively fixedly connected to the second upright plate 24. The outer side of the second upright plate 24 is fixedly connected to the outer side of the frame 1. A second rotating shaft 25 is fixedly connected inside one of the support arms 22. The second rotating shaft 25 passes through the first slide rod 6 and is rotatably connected to the first slide rod 6.

[0036] The position of the support arm 22 can be restricted by the second upright plate 24 and the first rotating shaft 23. The second rotating shaft 25 can connect one of the support arms 22 to the first sliding rod 6, thereby transmitting the pressure on the first sliding rod 6 to the support arm 22, thus improving the support. It can also allow the wheel 15 to move up and down within a certain range, so that the wheel 15 can always be in contact with the crane frame. This further reduces the possibility of the three wheels 15 bearing all the weight, thus reducing the possibility of the wheel 15 being overloaded and damaged.

[0037] The working principle and usage process of this utility model are as follows: The pressure borne by the frame 1 is transmitted to the first rotating seat 3, thereby transmitting power to the first connecting ring 4, which in turn transmits the pressure to the sleeve 5, and then to the fixed plate 7. This causes the sleeve 5 to slide outside the first sliding rod 6, compressing the spring 8. Subsequently, the pressure is transmitted to the second rotating seat 27, thus distributing the pressure. Through the cooperation of the first sliding rod 6, sleeve 5, fixed plate 7, and spring 8, when the frame 1 deforms, the sleeve 5 and the first sliding rod 6 can adjust their lengths under the action of the spring 8. This ensures that the wheels 15 can always contact the crane, reducing the possibility of all three wheels 15 bearing the entire weight, thus reducing the possibility of overloading the wheels 15 and causing damage, reducing potential maintenance time, and improving production efficiency.
