Description

Technical Field

[0001] This invention belongs to the field of engineering technology, specifically relating to a track thrust-stopping device and method. Background Technology

[0002] In bridge construction, various heavy-duty steel components, such as truck cranes, formwork cranes, and bridge deck cranes, need to be transported using rails. Current technology typically involves slotting the top plate of the steel rail and using gravity clamps or motor-locking mechanisms to achieve thrust control of the moving device. Traditional thrust control devices require a gap between the rail and the bridge deck to accommodate part of the thrust control structure during installation. Therefore, the application of traditional thrust control devices is limited in construction scenarios where vertical space is relatively confined. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a track thrust restraint device and method, which solves the problem that the application of existing thrust restraint devices is limited in construction scenarios with confined vertical space.

[0004] The technical solution of the present invention is as follows: A track thrust-stopping device includes a track and a first rotating shaft and a second rotating shaft disposed opposite to each other inside the track and rotatable in the vertical direction. The first rotating shaft is connected to a first stop block that can rotate with the first rotating shaft and can rotate from inside the track to outside the track. The second rotating shaft is connected to a second stop block that can rotate with the second rotating shaft and can rotate from inside the track to outside the track. The rotation paths of the first stop block and the second stop block are provided with limiting shafts for blocking the rotation of the first stop block and / or the second stop block.

[0005] Furthermore, the side of the track is provided with an elongated hole through which the first stop / second stop can pass. The elongated hole has a blocking part that can abut against the first stop / second stop. The first rotating shaft and the second rotating shaft can reciprocate longitudinally along the track under the drive of external force, so as to cooperate with the first stop / second stop to rotate together after abutting against the blocking part.

[0006] Furthermore, both the first and second blocks have a first state in which their ends protrude to the outside of the track and a second state in which they are housed inside the track.

[0007] Furthermore, when the first stop and the second stop are in the second state, the limiting shaft is located in front of the first stop and the second stop in the direction of movement, so that the limiting shaft has a convertible first position and a second position during reciprocating movement.

[0008] Furthermore, an elastic element for resetting the rotation angle is provided between the first rotating shaft and the second rotating shaft.

[0009] Furthermore, the elastic element is a detachable structure, and the elastic element is located on the front side of the first rotating shaft and the second rotating shaft in the direction of movement.

[0010] Furthermore, the track is provided with a housing for integrating the first rotating shaft, the second rotating shaft, the first stop, the second stop, and the limiting shaft. The housing is provided with a top cover and a lug for connecting the traction equipment.

[0011] A method for preventing track thrust using a track thrust device includes the following steps: S1) Determine the direction of movement of the thrust device; S2) Install the limiting shaft to the front side of the first and second stop blocks in the direction of their movement; S3) Install the elastic element to the front side of the first and second rotating shafts in the direction of movement; S4) Drive the traction device. When it is necessary to change the direction of movement, execute steps S2) to S3 again.

[0012] Due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows: 1. The technical solution of this application achieves thrust by modifying the side of the track and rotating the stop, which eliminates the need to reserve a gap between the track and the mounting surface and saves vertical installation space during construction.

[0013] 2. This application does not impede the normal transport function of the track while stopping the thrust.

[0014] 3. This application can achieve thrust in two directions of movement, and the direction of movement can be changed by changing the corresponding components. Attached Figure Description

[0016] To more clearly illustrate the overall concept of this application, a detailed description is provided below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application; however, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below. Based on the background technology described, as shown in the appendix Figure 1 As shown, some construction sites present situations where vertical space is relatively limited. Heavy-duty steel components are typically transported via rail, usually with double-supported rails. A hydraulic cylinder is installed in the middle of the double-supported rails to drive a support frame for component transport. Components need to stop at appropriate locations during transport, therefore, appropriate devices must be designed to prevent the drive mechanism from moving.

[0017] As attached Figure 2 As shown, a track 1 thrust-stopping device includes a track 1 and a first rotating shaft 2-1 and a second rotating shaft 2-2 disposed opposite to each other inside the track 1 and rotatable in the vertical direction. The first rotating shaft 2-1 is connected to a first stop block 3-1 that can rotate with it and can rotate from inside the track 1 to outside the track 1. The second rotating shaft 2-2 is connected to a second stop block 3-2 that can rotate with it and can rotate from inside the track 1 to outside the track 1. The rotation path of the first stop block 3-1 and the second stop block 3-2 is provided with a limiting shaft 4 for blocking the rotation of the first stop block 3-1 and / or the second stop block 3-2.

[0018] The first rotating shaft 2-1 is connected to the first stop block 3-1, and the second rotating shaft 2-2 is connected to the second stop block 3-2. The first rotating shaft 2-1 and the second rotating shaft 2-2 can be symmetrically arranged along the longitudinal direction of the track 1. When the first rotating shaft 2-1 and the second rotating shaft 2-2 move along the longitudinal direction of the track 1, they can simultaneously pull the first stop block 3-1 and the second stop block 3-2 to move together. After the first stop block 3-1 / the second stop block 3-2 rotates to the outside of the track 1 and encounters resistance, the first stop block 3-1 / the second stop block 3-2 will rotate towards the inside of the track 1, thereby driving the first rotating shaft 2-1 / the second rotating shaft 2-2 to rotate. After the limiting shaft 4 is set, the stop block will be limited at the corresponding angle and stop rotating. After stopping rotating, it will fit against the inside of the track 1 and can finally move within the track 1.

[0019] As a preferred embodiment of this application, see the attached document. Figure 1 and attached Figure 2As shown, the side of the track 1 is provided with an elongated hole 5 through which the first stop 3-1 / second stop 3-2 can pass. The elongated hole 5 has a blocking part 6 that can abut against the first stop 3-1 / second stop 3-2. The first rotating shaft 2-1 and the second rotating shaft 2-2 can reciprocate longitudinally along the track 1 under the drive of external force, so as to cooperate with the first stop 3-1 / second stop 3-2 to abut against the blocking part 6 and rotate together.

[0020] As attached Figure 1 As shown, the elongated hole 5 is located on the side of the track 1 and can be rectangular, accommodating the first stop block 3-1 / second stop block 3-2. The two sides of the elongated hole 5 are blocking parts 6, which provide resistance to the movement of the stop block, causing it to rotate, or work in conjunction with the limiting shaft 4 to achieve thrust prevention: When the cylinder 10 is pushed out (the device is preparing to move to the right), the first rotating shaft 2-1 / second rotating shaft 2-2 is first pushed to the left, causing the first stop block 3-1 / second stop block 3-2 to abut against the blocking part 6 on the left. At this time, the first stop block 3-1 has a tendency to rotate to the right (the second stop block 3-2 is the opposite). After being limited by the limiting shaft 4, the thrust prevention device remains stationary, achieving thrust prevention; When the cylinder 10 is pushed back out (during the device's rightward movement), the stop block abuts against the blocking part 6 on the right. At this time, the stop block has a tendency to rotate to the left. Without the limiting effect of the limiting shaft 4, the stop block can be stored in the track 1 and move with the track 1.

[0021] In the above embodiment, both the first stop 3-1 and the second stop 3-2 have a first state in which their ends protrude to the outside of the track 1 and a second state in which they are housed inside the track 1. When the first stop 3-1 and the second stop 3-2 are in the second state, the limiting shaft 4 is located in front of the first stop 3-1 and the second stop 3-2 in the direction of movement, so that the limiting shaft 4 has a convertible first position and a second position during reciprocating movement.

[0022] As attached Figure 3 and attached Figure 4 As shown, in actual use, the thrust stop device must both reciprocate with the traction equipment and provide thrust at appropriate positions. Therefore, the stop block should have two states: one for movement and one for thrust. In the first state, the stop block provides thrust, preventing the traction equipment from moving. In the second state, the stop block is retracted into track 1 and moves with the traction equipment. However, when changing the direction of movement, the position of the limit shaft 4 should be reversed to change the thrust / movement direction.

[0023] In one specific embodiment of the above implementation method, the limiting shaft 4 is installed in the hole of the limiting shaft 4. After the hole of the limiting shaft 4 is set at the position shown in the figure of the rotation path of the stop, the simple replacement can be achieved by the detachable limiting shaft 4.

[0024] In a preferred embodiment of the above embodiments, an elastic element 8 for resetting the rotation angle is provided between the first rotating shaft 2-1 and the second rotating shaft 2-2. In specific implementation, the elastic element 8 can be a tension spring. Pins are provided on the first rotating shaft 2-1 and the second rotating shaft 2-2. After the tension spring is installed on the pins, when the first rotating shaft 2-1 and the second rotating shaft 2-2 rotate outward from the track 1 (the stop changes from the first state to the second state), the tension spring is stretched and accumulates potential energy; when the stop moves to the elongated hole 5, the potential energy is released, causing the rotating shaft to reset, and the stop is in the second state. In specific implementation, pins for installing tension springs can be provided on both the front and rear sides of the rotating shaft. When it is necessary to change the direction of movement, the positions of the tension spring and the limiting shaft 4 are changed simultaneously. The positions of the tension spring and the limiting shaft 4 should always be on one side of the forward direction.

[0025] As attached Figure 2 ~Appendix Figure 4 As shown in a preferred embodiment of this application, the track 1 has a housing 9 inside for integrating the first rotating shaft 2-1, the second rotating shaft 2-2, the first stop block 3-1, the second stop block 3-2, and the limiting shaft 4. The housing 9 has a top cover 9-1 and ear plates 9-2 for connecting the traction equipment. After integrating all parts into a whole, the traction equipment is connected through the ear plates 9-2 to realize the movement of the thrust device. High-strength bolts are also provided at the front and rear of the housing 9 to withstand the shear force generated during traction.

[0026] A method for preventing thrust on a track includes the following steps: S1) Determine the direction of movement of the thrust device; that is, the forward and backward directions of the track.

[0027] S2) Install the limit shaft to the front side of the first and second stops in the direction of movement. (See attached diagram) Figure 3 As shown, in the forward direction illustrated, the limit shaft should be installed at the position shown above the stop block.

[0028] S3) Install the elastic element to the front side of the first and second rotating shafts in the direction of movement.

[0029] When the elastic element and the limiting shaft are installed on the same side, the thrust device can move and stop thrust.

[0030] S4) Drive the traction device. When it is necessary to change the direction of movement, execute steps S2) to S3 again.

[0031] As attached Figure 3 and attached Figure 4 As shown, the position of the limit axis should be changed when the forward direction changes.
