Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a bridge body safety supporting bracket. Background Art

[0002] An assembled bridge is a bridge body that is formed in a prefabricated component factory and then transported to the construction site for hoisting and splicing. When the assembled bridge is being spliced ​​and constructed, a safety support bracket is required to temporarily support and lift the bridge body. For example, the patent with application number: CN202221464373.0 discloses a bridge body safety support bracket for assembled bridge construction, which can meet the support requirements of different heights. The overall support has strong stability when it is on the ground, and it is convenient to move the whole body during non-construction periods. However, when the existing bridge body safety support bracket such as the above-mentioned one is in use, the moving wheels of the bracket need a set of exclusive drive components to control whether it is in use. This results in too many drive components on the bracket, causing the overall weight of the support bracket to increase, making it inconvenient to move the support bracket. Summary of the invention

[0003] The disclosed embodiment relates to a bridge body safety support bracket, which, when a scissor lift controls the support plate to rise, cooperates with multiple structures to make the brake disc contact with the friction disc, causing friction between the two discs and utilizing the friction to brake and position the traveling wheels, making it impossible for the traveling wheels to move, thereby ensuring the stability of the support bracket after it is put into use.

[0004] In a first aspect of the present disclosure, a bridge safety support bracket is provided, which specifically includes: a supporting body, a scissor lift is fixedly installed on the top of the supporting body; a supporting tray with a rectangular structure is installed on the top of the scissor lift; a trigger mainboard with a rectangular structure is fixedly installed on the left and right sides of the bottom of the supporting tray; running wheels are rotatably installed on the front and rear sides of the bottom of the supporting body; a disc-shaped friction disk is fixedly installed inside the running wheel; a mounting seat is fixedly installed on the left and right sides of the bottom of the supporting body; a transmission slide bar with a cylindrical structure is slidably installed on the mounting seat; a connecting cross bar is fixedly installed on the outer end of the transmission slide bar; and a brake disc with a disc-shaped structure is fixedly installed on the inner end of the connecting cross bar.

[0005] In at least some embodiments,

[0006] The position of the brake disc corresponds horizontally to that of the friction disc; a driven slide is fixedly installed on the top of the transmission slide rod; the inner end of the top of the driven slide is an inclined structure; and trigger columns of a cylindrical structure are fixedly installed on the front and rear sides of the driven slide.

[0007] In at least some embodiments,

[0008] A disc-shaped embedded baffle is fixedly installed on the inner end of the transmission slide rod; a transverse spring is embedded between the two embedded baffles; a guide seat is fixedly installed on the outer side of the mounting seat; a positioning plug plate with a triangular bottom end is slidably installed inside the guide seat.

[0009] In at least some embodiments,

[0010] The outer wall of the positioning plug plate is provided with a driven groove of an inclined structure; the trigger column is also slidably installed inside the driven groove; an embedded baffle is fixedly installed on the top of the positioning plug plate; a vertical spring is embedded between the bottom of the embedded baffle and the top of the guide seat.

[0011] The utility model provides a bridge body safety support bracket, which has the following beneficial effects:

[0012] 1. When the safety support bracket is lifting and supporting the bridge body, it will control the contact between the brake disc and the friction disc with the cooperation of the corresponding structure, so that the brake disc and the friction disc cooperate to achieve the braking positioning of the running wheel, ensuring that the support bracket will not move when lifting and supporting the bridge body, thereby improving the safety and stability of the support bracket when in use.

[0013] 2. When the brake disc and the friction disc contact and position the travel wheel, the safety support bracket can press down the positioning plate through the coordination of the structure, so that the positioning plate is inserted into the ground by pressing down. The insertion of the positioning plate can further enhance the stability of the support bracket during use and improve the safety of the support bracket.

[0014] 3. This safety support bracket can automatically brake the traveling wheels and insert the positioning plug into the ground when the scissor lift lifts the bridge body. At the same time, when the scissor lift is lowered and no longer needed, it can automatically restore the traveling wheels to a walking state and automatically pull the positioning plug out of the ground. This can effectively control the state of the traveling wheels without the need to equip the state control work with a dedicated drive component, effectively reducing the weight of the support bracket and facilitating the movement of the support bracket.

Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Please refer to Figures 1 to 6 :

[0029] Embodiment 1:

[0030] The utility model proposes a bridge body safety support bracket, comprising: a supporting body 1, a scissor lift 2 is fixedly installed on the top of the supporting body 1; a supporting support plate 3 with a rectangular structure is installed on the top of the scissor lift 2; a trigger mainboard 19 with a rectangular structure is fixedly installed on the left and right sides of the bottom of the supporting support plate 3; running wheels 4 are rotatably installed on the front and rear sides of the bottom of the supporting body 1; a disc-shaped friction disk 5 is fixedly installed inside the running wheel 4; a mounting seat 6 is fixedly installed on the left and right sides of the bottom of the supporting body 1; a transmission slide bar 7 with a cylindrical structure is slidably installed on the mounting seat 6; a connecting cross bar 8 is fixedly installed on the outer end of the transmission slide bar 7; and a brake disc 9 with a disc-shaped structure is fixedly installed on the inner end of the connecting cross bar 8.

[0031] The supporting vehicle body 1 and the bridge body waiting for assembly support are transported to a suitable position by the traveling wheels 4, and then the scissor lift 2 is started to move upward with the supporting pallet 3 and the bridge body, so that the height of the bridge body is in a suitable state, which is convenient for assembling the bridge body.

[0032] Embodiment 2, on the basis of embodiment 1, the position of the brake disc 9 corresponds horizontally to the position of the friction disc 5; a driven slide 10 is fixedly installed on the top of the transmission slide bar 7; the inner end of the top of the driven slide bar 10 is an inclined structure; a trigger column 11 of a cylindrical structure is fixedly installed on the front and rear sides of the driven slide bar 10; an embedded baffle 12 of a disc-shaped structure is fixedly installed on the inner end of the transmission slide bar 7; a transverse spring 13 is embedded between the two embedded baffles 12.

[0033] When the scissor lift 2 moves upward with the supporting pallet 3, the supporting pallet 3 will also move upward with the trigger main board 19, so that the trigger main board 19 cancels the limit on the two driven slides 10 by rising, and the two driven slides 10 and the two transmission slides 7, the two connecting cross bars 8 and the two brake discs 9 move inward relative to each other under the action of the transverse spring 13, so that the two brake discs 9 come into friction contact with the friction disc 5 by moving inward, so as to utilize the friction between the brake disc 9 and the friction disc 5 to brake and limit the travel wheel 4, so as to avoid the support pallet 3 from supporting the vehicle body 1 when lifting the bridge body and assembling the bridge body, thereby ensuring the support stability and the safety of the staff below.

[0034] Embodiment 3, on the basis of embodiment 2, a guide seat 14 is fixedly installed on the outer side of the mounting seat 6; a positioning plug plate 15 with a triangular structure at the bottom end is slidably installed inside the guide seat 14; a driven groove 16 with an inclined structure is provided on the outer wall of the positioning plug plate 15; the trigger column 11 is also slidably installed inside the driven groove 16; an embedded baffle 17 is fixedly installed on the top of the positioning plug plate 15; a vertical spring 18 is embedded between the bottom of the embedded baffle 17 and the top of the guide seat 14.

[0035] When the driven slide plate 10 slides inward, the driven slide plate 10 will also move inward with the trigger column 11. During the movement, since the trigger column 11 is also slidably installed inside the driven groove 16, and the driven groove 16 is an inclined structure, the inward translation force of the trigger column 11 will be converted into a downward force by the driven groove 16 and provided to the positioning plug plate 15, so that the positioning plug plate 15 can be inserted into the ground through the downward force using the triangular structure at its bottom end, thereby utilizing the insertion of the positioning plug plate 15 to enhance the stability of the support bracket when in use.

[0036] The working principle of this embodiment:

[0037] When in use, firstly, the supporting vehicle body 1 and the bridge body to be supported by the traveling wheels 4 are transported to a suitable position, and then the scissor lift 2 is started to move upward with the supporting pallet 3 and the bridge body, so that the height of the bridge body is in a suitable state, which is convenient for assembling the bridge body, and when the scissor lift 2 moves upward with the supporting pallet 3, the supporting pallet 3 will also move upward with the trigger main board 19, so that the trigger main board 19 cancels the limit of the two driven slides 10 by rising, so that the two driven slides 10 and the two transmission slides 7, the two connecting cross bars 8 and the two brake discs 9 move inwardly relative to each other under the action of the transverse spring 13, so that the two brake discs 9 rub against the friction disc 5 by moving inward. The friction between the brake disc 9 and the friction disc 5 is used to brake and limit the walking wheel 4, so as to prevent the support plate 3 from supporting the vehicle body 1 when the bridge body is lifted and the bridge body is assembled. Moreover, when the driven slide plate 10 slides inward, the driven slide plate 10 will also move the trigger column 11 inward. During the movement, since the trigger column 11 is also slidably installed inside the driven groove 16, and the driven groove 16 is an inclined structure, the inward translation force of the trigger column 11 will convert the driven groove 16 into a sliding force provided to the positioning plug plate 15, so that the positioning plug plate 15 is inserted into the ground through the sliding force using the triangular structure at its bottom end, thereby utilizing the insertion of the positioning plug plate 15 to enhance the stability of the support bracket when in use.
