[0025] like Figure 1 , Figure 2, Figure 3 As shown, a temporary support device for road and bridge construction includes a base 1, a cylinder 2 is fixedly installed on the top surface of the base 1, and a top plate 3 is fixedly connected to the telescopic end of the cylinder 2. A support mechanism 4 for supporting the top plate 3 is provided on the surface of the base 1, and a manual adjustment mechanism 5 is also provided on the surface of the base 1. A transport auxiliary mechanism 6 is provided on the left and right sides of the base 1, and a positioning mechanism 7 for limiting the transport auxiliary mechanism 6 is provided on the surface of the base 1. More specifically, the bracket is transported to the location to be supported, the contact between the transport auxiliary mechanism 6 and the ground is released, and the state of the transport auxiliary mechanism 6 is locked by the positioning mechanism 7, so that the bottom surface of the base 1 is in contact with the ground, and the top plate 3 is driven to rise and fit with the support position by the cylinder 2, so as to support it through the top plate 3, and then the support mechanism 4 is driven to operate by the manual adjustment mechanism 5 to strengthen the support of the bottom of the top plate 3.

[0026] like Figure 1 As shown, the support mechanism 4 includes an adjusting screw rod 401, and the adjusting screw rod 401 is rotatably connected to the base 1, a threaded block 402 is threadedly connected to the surface of the adjusting screw rod 401, a support column 403 is fixedly connected to the surface of the threaded block 402, a guide tube 404 is fixedly connected to the surface of the support column 403, and support rods 405 are fixedly connected to the four corners of the top surface of the base 1, and the guide tube 404 is slidably sleeved with the support rod 405. It should be noted that the adjusting screw rod 401 is controlled to rotate by the manual adjustment mechanism 5, thereby driving the threaded block 402 to move under the action of the thread, and then driving the support column 403 to move, thereby pulling the guide tube 404 to slide along the surface of the support rod 405, so that the top of the guide tube 404 fits with the bottom of the top plate 3, thereby supporting the bottom of the top plate 3.

[0027] like Figure 1 , Figure 2 As shown, the manual adjustment mechanism 5 includes a worm 501, and the worm 501 is rotatably connected to the base 1, a handle 502 is fixedly connected to the front end of the worm 501, a worm wheel 503 is fixedly sleeved on the surface of the adjusting screw 401, and the worm 501 is meshingly arranged with the worm wheel 503. More specifically, by rotating the handle 502, the worm 501 is driven to rotate, and then the worm wheel 503 meshing with it is driven to rotate, thereby controlling the rotation of the adjusting screw 401.

[0028] like Figure 3As shown, the carrying auxiliary mechanism 6 includes a rotating column 601, and the rotating column 601 is rotatably connected to the base 1. A supporting leg 602 is fixedly sleeved on the surface of the rotating column 601, and a moving wheel 603 is arranged at the end of the supporting leg 602. The left side and the right side of the base 1 are both provided with a receiving groove 604, and the supporting leg 602 is located inside the receiving groove 604. The rear end of the rotating column 601 is fixedly connected with a knob 605. It should be noted that by rotating the knob 605, the rotating column 601 is driven to rotate, and then the supporting leg 602 and the moving wheel 603 are driven to rotate, so that the moving wheel 603 is in a horizontal state, and the bottom of the base 1 can be released from the ground, so as to provide stable support. When moving is required, the moving wheel 603 can be rotated to a vertical state and contact with the ground, and can be quickly moved in conjunction with the rolling of the moving wheel 603.

[0029] like Figure 3 , Figure 4 As shown, the positioning mechanism 7 includes a fixed box 701, and the fixed box 701 is fixedly connected to the back of the base 1, the inner wall of the fixed box 701 is slidably connected to a connecting block 702, the top surface of the connecting block 702 is fixedly connected to a supporting spring 704, and the top of the supporting spring 704 is fixedly connected to the inner wall of the fixed box 701, a pull rod 705 is fixedly connected to the middle of the top surface of the connecting block 702, and a positioning block 703 is fixedly connected to the bottom of the connecting block 702, and a positioning gear 706 is fixedly sleeved on the surface of the rotating column 601, and the positioning block 703 is fixedly connected to the inner wall of the fixed box 701. The surface of the positioning gear 706 is movably plugged in. More specifically, under the elastic force of the support spring 704, the connecting block 702 tends to move downward, thereby firmly pressing the positioning block 703 on the surface of the positioning gear 706, so that the positioning gear 706 cannot rotate, thereby limiting the rotating column 601. By pulling the pull rod 705, the connecting block 702 is driven to move upward, thereby compressing the support spring 704, which can drive the positioning block 703 to leave the surface of the positioning gear 706, and the limit can be released.

[0030] like Figure 3 As shown, a compression pad 8 is fixedly connected to the top surface of the top plate 3, and the compression pad 8 is made of rubber. It should be noted that by providing the compression pad 8 made of rubber, the friction with the support position is increased, and the vibration of the support position can be absorbed, making the support more stable.

[0031] To sum up: the bracket is transported to the location to be supported, the contact between the transport auxiliary mechanism 6 and the ground is released, and the state of the transport auxiliary mechanism 6 is locked by the positioning mechanism 7, so that the bottom surface of the base 1 is in contact with the ground, and the top plate 3 is driven to rise and fit with the support position by the cylinder 2, so as to provide support through the top plate 3, and then the support mechanism 4 is driven to operate by the manual adjustment mechanism 5 to strengthen the support of the bottom of the top plate 3. During use, the effect of effective support for the road and bridge construction position is achieved, the support height can be flexibly adjusted, the adjustment process is very convenient, and the disadvantages of the moving wheel support are avoided. When supporting, the entire bracket is more stable and not prone to shaking.
