Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of concrete prefabricated part transmission, and more particularly to a concrete prefabricated part transmission support device for bridge construction. BACKGROUND

[0002] In the process of bridge construction, concrete prefabricated parts are widely used in bridge engineering because of controllable quality, fast construction speed, and reduced environmental impact of on-site operations. Concrete prefabricated parts are prefabricated in factories or on site, and then transported to the site for installation and splicing. Concrete prefabricated parts can be customized according to the required shape, size, and purpose. Common prefabricated parts include wall panels, staircases, beams, columns, and boards.

[0003] Concrete prefabricated parts are prefabricated in factories and then transported to the construction site for assembly, which can effectively shorten the construction period. During the movement and transportation of concrete prefabricated parts, a transmission support mechanism is needed for support. However, the existing transmission support mechanism generally uses a stacking method, and the bottom layer of concrete prefabricated parts is easily damaged due to excessive pressure during the stacking process. However, if the stacking is not used or the number of stacked concrete prefabricated parts is small, the vertical space cannot be fully utilized, resulting in space waste. In addition, when a large number of concrete prefabricated parts are stacked, they are easily displaced during transportation due to sudden braking or stopping, causing the device to tip over. It is difficult to ensure the stability of the transmission support device during high-speed transmission. SUMMARY

[0039] Among them, clamping block 23 is inserted and installed in the inside of bottom sleeve 13, and the bottom of reinforcing rod 26 is inserted and installed in the inside of positioning sleeve 14, and reinforcing rod 26 is inserted and embedded in the inside of positioning frame 25 of the side of multiple base frames 21, to increase the connection between multiple base frames 21, so that transmission support frames 2 are more stable, and at the same time, the support strength of the side of base frame 21 is improved by using reinforcing rod 26.

[0041] Second embodiment

[0042] As shown in the accompanying drawings Figure 1 to the accompanying drawings Figure 5 , the accompanying drawings Figure 9 As an embodiment of the present application, since a plurality of precast blocks 4 are stacked, the height of the stacking is high, and the device is prone to tilt due to sudden braking or stopping, which causes the center of gravity of the goods to deviate and the stability of the transmission support device to be difficult to guarantee. By setting the balance detection assembly 3, the moving state of the transmission support device is detected, and the position of the counterweight block 168 inside the base shell 11 is controlled by the controller 32, the center of gravity of the transmission support device is adjusted, and the stability of the transmission support device is improved, thereby avoiding the inclination of the transmission support device.

[0059] Similarly, when the transmission preform suddenly stops during moving to the left side, the moving block 36 continues to move left due to inertia and touches the second touch button 35, so that the fixed sleeve frame 166 drives the counterweight 168 to move to the right inside the base shell 11, so that the center of gravity of the transmission support device moves to the right to avoid tilting to the left due to inertia;

[0060] When the fixed sleeve frame 166 drives the counterweight 168 to move to one side inside the base shell 11, the connecting seat 163 in the opposite direction pulls the corresponding first steel wire rope 165 to move, so that the pulling spring 164 is further stretched, the extrusion roller 127 generates a force opposite to the inertial motion of the preform block 4, and the side of the preform block 4 is extruded, thereby resisting the side movement of the preform block 4 due to inertia, thereby maintaining the stability of each layer of preform block 4, further improving the stability of the transmission support device. At the same time, when the preform block 4 is extruded to the extrusion roller 127, the rotating frame 124 rotates, further pulling the second steel wire rope 126, and through the reaction force of the pulling spring 164, buffering the preform block 4 to avoid damage to the preform block 4 extruded to the rigid positioning frame 12.

[0061] Finally, it should be pointed out that: the drawings of the disclosed embodiments only involve the structures involved in the disclosed embodiments, other structures can be referred to the usual design, and in the case of no conflict, the same embodiments and different embodiments of the present application can be combined with each other;

[0062] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
