Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering, and in particular to an automatic lifting device for tank trucks. Background Technology

[0002] The tank truck is primarily responsible for supporting and securing the embedded parts of the portal frame, expanding and contracting the lateral formwork of the connecting beam, lifting and securing the bottom formwork of the connecting beam, expanding and contracting the upstream formwork, and providing a platform for personnel construction and equipment storage. Currently, lifting the tank truck requires workers to erect hoists around the top of the truck, resulting in a significant waste of manpower and resources. Furthermore, welding and positioning the tank truck with the embedded parts of the portal frame requires a tower crane, a series of cumbersome operations that consume considerable time and manpower, impacting the overall construction progress. This reduces construction efficiency, increases construction costs, and compromises construction safety. Therefore, we propose an automatic lifting device for the tank truck to solve these problems. Utility Model Content

[0003] This utility model provides an automatic lifting device for tank trucks, which solves the problem that workers need to set up hoists around the top of the tank truck for lifting, resulting in a waste of a lot of manpower and resources. At the same time, it avoids the need for tower cranes to lift the tank truck and the embedded parts of the gate, which are cumbersome and consume a lot of time and manpower, affecting the overall construction progress.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an automatic lifting device for a tank car, including a pier, a tank car on the pier, a plurality of climbing mechanisms on the tank car, the climbing mechanism including a slide rail, a lifting cylinder and two steering boxes, a plurality of U-shaped door slots on the pier, a plurality of climbing formwork hangers on the pier, and a rotating wedge-shaped block at one end of the slide rail.

[0005] In the preferred embodiment, the tanker is equipped with an installation frame, which has multiple platforms. Multiple screw sleeves are provided on both sides of the platforms, and screws are provided at both ends of the screw sleeves. The two screws abut against the two ends of the U-shaped gate slot respectively.

[0006] In a preferred embodiment, the steering box includes a housing, which is slidably connected to the slide rail. The top steering box is mounted on the tank car, and two steering boxes are connected to the slide rail. A lifting cylinder is provided between the two steering boxes.

[0007] In a preferred embodiment, a motor is mounted on the housing, the output shaft of the motor is equipped with a hammer-shaped climbing head, the conical end of the hammer-shaped climbing head is equipped with a hinged spring buffer, and one end of the spring buffer is equipped with a spring buffer seat plate.

[0008] In the preferred embodiment, the spring buffer seat plate is rotatably connected to the housing, the top of the slide rail is provided with a side groove, the side groove is provided with a wedge-shaped block, one end of the wedge-shaped block is rotatably connected to the slide rail, and the other end of the wedge-shaped block is provided with a cylinder between it and the slide rail.

[0009] In the preferred embodiment, the housing is provided with an upper crossbeam, a lower crossbeam, and multiple step stops, which are installed on the slide rail;

[0010] The upper crossbeam is used to contact and limit the upper end face of the hammer-shaped climbing head; the upper bearing surface of the hammer-shaped climbing head is used to abut against the lower end face of the ladder rung.

[0011] In the preferred embodiment, the slide rail is an I-beam structure, and a second U-shaped groove is provided on one side of the housing, with one side of the slide rail abutting against the second U-shaped groove.

[0012] In the preferred embodiment, a U-shaped groove is provided on one side of the climbing formwork bracket, the slide rail slides against the U-shaped groove, and the top steering box is installed on the platform.

[0013] In the preferred embodiment, a tie rod is provided between the two opposing U-shaped door slots.

[0014] The beneficial effects of this utility model are as follows: When the tank car needs to rise, the two steering boxes of the climbing mechanism are driven, causing the motor of the bottom steering box to rotate, so that the upper bearing surface of the hammer-shaped climbing head abuts against the lower end surface of the ladder rung. This connects the bottom steering box with the slide rail. Simultaneously, the top steering box is driven, causing it to release the slide rail. The screws on the top of the tank car are then driven, causing multiple screws to abut against the U-shaped portal groove, thus fixing the tank car to the U-shaped portal groove and the pier. The lifting cylinder is then driven, causing the slide rail to slide relative to the tank car and the pier, thereby raising the slide rail.

[0015] When the slide rail does not rise far enough, the top steering box is driven to connect with the slide rail, while the bottom steering box is released from the slide rail. The lifting cylinder is extended to allow the bottom steering box to slide down the slide rail. When the lifting cylinder is at its longest, the two steering boxes reverse direction, and the lifting cylinder retracts until the slide rail rises to its position.

[0016] Once the slide rail is raised to its position, the cylinder at the top of the slide rail is driven to rotate the wedge-shaped locking block relative to the slide rail, so that the wedge-shaped locking block is locked on the climbing formwork bracket, and the positioning of multiple slide rails is completed.

[0017] The climbing mechanism consists of two steering boxes. The bottom steering box connects to the slide rail, while the upper bearing surface of the hammer-shaped climbing head of the top steering box abuts against the lower end face of the ladder rung. When the top steering box releases the slide rail, the screw on top of the tank car moves away from the U-shaped portal, extending the lifting cylinder to raise the tank car. Once the tank car is in position, the screw is rotated to position it. The climbing mechanism automatically raises and lowers the tank car, adjusting the lifting height. This avoids the need for workers to erect hoists around the top of the tank car for lifting, which wastes significant manpower and resources. It also avoids the need for tower cranes to lift the tank car and portal embedded parts, which poses safety risks such as falling objects and personnel falling from heights. Operational errors or equipment malfunctions can easily lead to accidents. The mechanism offers low labor costs, high construction efficiency, and significant potential for widespread adoption.

Detailed Implementation

[0032] Example 1:

[0033] like Figures 1-12 An automatic lifting device for tank trucks includes a pier 1, on which a tank truck 2 is mounted. The tank truck 2 has multiple climbing mechanisms 3, each including a slide rail 5, a lifting cylinder 14, and two steering boxes 4. The pier 1 has multiple U-shaped door slots 11 and multiple climbing formwork hangers 6. One end of the slide rail 5 has a rotating wedge-shaped locking block 502. With this structure, when the tank truck 2 needs to rise, the two steering boxes 4 of the climbing mechanism 3 are driven, causing the motor 401 of the bottom steering box 4 to rotate, so that the upper bearing surface of the hammer-shaped climbing head 402 abuts against the lower end surface of the step 406, thus connecting the bottom steering box 4 to the slide rail 5. Simultaneously, drive the top steering box 4 to release the slide rail 5, drive the screw 204 on the top of the tank car 2 to make multiple screws 204 abut against the U-shaped gate slot 11, so that the tank car 2 is fixed to the U-shaped gate slot 11, so that the tank car 2 is fixed to the pier body 1, drive the lifting cylinder 14 to make the slide rail 5 slide relative to the tank car 2 and the pier body 1, so that the slide rail 5 rises.

[0034] When the slide rail 5 does not rise far enough, drive the top steering box 4 to connect the top steering box 4 with the slide rail 5, and release the bottom steering box 4 from the slide rail 5. Extend the lifting cylinder 14 so that the bottom steering box 4 slides down along the slide rail 5. When the lifting cylinder 14 is at its longest, the two steering boxes 4 reverse direction and retract the lifting cylinder 14 until the slide rail 5 rises to the correct position.

[0035] Once the slide rail 5 is in position, the cylinder at the top of the slide rail 5 is driven to rotate the wedge-shaped locking block 502 relative to the slide rail 5, so that the wedge-shaped locking block 502 is locked on the climbing formwork bracket 6, and the positioning of multiple slide rails 5 is completed.

[0036] The two steering boxes 4 of the driving climbing mechanism 3 connect the bottom steering box 4 to the slide rail 5, and the upper bearing surface of the hammer-shaped climbing head 402 of the top steering box 4 abuts against the lower end surface of the ladder rung 406. The top steering box 4 releases the slide rail 5, the screw 204 on the top of the tank car 2 moves away from the U-shaped gate slot 11, and the lifting cylinder 14 extends, raising the tank car 2. After the tank car 2 is in position, the screw 204 of the tank car 2 is rotated to position the tank car 2. The climbing mechanism 3 can automatically raise and lower, and the lifting height can be adjusted. This avoids the need for workers to set up hoists around the top of the tank car for lifting, which wastes a lot of manpower and resources. It also avoids the need for tower cranes to lift the tank car 2 and the gate slot embedded parts, which poses safety risks such as falling objects and personnel falling from heights. Operational errors or equipment malfunctions can easily lead to safety accidents. The system has low labor costs and high construction efficiency.

[0037] In the preferred embodiment, the tank truck 2 is equipped with a mounting frame 201, which has multiple platforms 202. Multiple screw sleeves 203 are located on both sides of each platform 202, and screws 204 are located at both ends of each screw sleeve 203. Two screws 204 abut against both ends of the U-shaped portal groove 11. With this structure, rotating the screws 204 causes them to rotate relative to the screw sleeves 203. When both screws 204 abut against the U-shaped portal groove 11, the tank truck 2 is connected and positioned to the U-shaped portal groove 11, thus positioning the tank truck 2 to the pier body 1. A washer is provided at one end of each screw 204, and this washer abuts against the U-shaped portal groove 11. When multiple horizontal washeres abut against the U-shaped portal groove 11, the tank truck 2 can be leveled, preventing it from deflecting.

[0038] In a preferred embodiment, the turning box 4 includes a housing, which is slidably connected to the slide rail 5. The top turning box 4 is mounted on the tank car 2, and two turning boxes 4 are connected to the slide rail 5. A lifting cylinder 14 is provided between the two turning boxes 4. With this structure, the slide rail 5 slides against the U-shaped groove of the climbing formwork bracket 6. When the tank car 2 needs to rise, the two turning boxes 4 of the climbing mechanism 3 are driven to rotate the motor 401 of the bottom turning box 4, so that the upper bearing surface of the hammer-shaped climbing head 402 abuts against the lower end surface of the step 406, thereby connecting the lower turning box 4 to the slide rail 5. At the same time, the top turning box 4 is driven to release the slide rail 5, drive the screw 204 on the top of the tank car 2, so that multiple screws 204 abut against the U-shaped gate groove 11, thereby fixing the tank car 2 to the U-shaped gate groove 11 and fixing the tank car 2 to the pier body 1. The lifting cylinder 14 is driven to make the slide rail 5 slide relative to the tank car 2 and the pier body 1, thereby raising the slide rail 5.

Thus, the upper crossbeam 407 is used to contact and limit the upper end face of the hammer-shaped climbing head 402. A lower crossbeam 408 is fixed to the top of the housing, and the lower crossbeam 408 is used to contact and limit the lower end face of the hammer-shaped climbing head 402; the lower bearing surface of the hammer-shaped climbing head 402 is used to abut against the upper end face of the step 406.

[0043] The drive motor 401 rotates the hammer-shaped climbing head 402, which compresses the spring of the spring buffer 403. After passing the balance middle position, the spring relaxes, and the motor 401 drives the hammer-shaped climbing head 402 to rotate at the same time, so that the upper bearing surface of the hammer-shaped climbing head 402 abuts against the bottom of the step 406, and the other end of the hammer-shaped climbing head 402 abuts against the bottom end of the upper crossbeam 407, so that the turning box 4 is connected to the slide rail 5.
