Please refer to Fig. 1-4, an embodiment provided by the utility model: a road and bridge support bracket, comprising:

Bottom plate 1, a push handle 2 is welded on one side of the outer wall of the bottom plate 1, and the four corners of the bottom of the bottom plate 1 are fixedly connected with support rods 4, and the bottom of the support rod 4 is installed with a shock absorber 5, and the bottom of the shock absorber 5 is connected by bolts and threads There are universal wheels 6;

Stairs 3, the top of the bottom plate 1 near the edge of one side is fixedly connected with a stair 3, the two sides of the stair 3 are fixedly equipped with handrails, and the upper surface of the inner steps of the stair 3 is equipped with a non-slip mat. There may be a danger of slipping when people climb up the stairs 3, and the setting of handrails and anti-slip mats effectively prevents the staff from slipping and falling when going up the steps;

Support frame 7, the bottom of base plate 1 is welded with support frame 7, and the quantity of support frame 7 is provided with two groups, and the inside of support frame 7 is inserted with supporting soil nail 9 along horizontal direction, and the quantity of supporting soil nail 9 is at least There are three groups, the other end of the supporting soil nails 9 is threadedly connected to the hinged plate 8, the connection between each group of supporting soil nails 9 and the hinged plate 8 is threaded, and the supporting soil nails 9 pass through the hinged plate 8 along the vertical direction. Inside, as shown in accompanying drawing 1, since it is a support bracket used in road and bridge construction or maintenance work, the bracket needs to have certain support and stability, and the setting of supporting soil nail 9 is connected through the internal screw connection of hinge plate 8 , so that the staff can drive the supporting soil nails 9 below the ground according to the needs, so that the bracket as a whole has a certain stability;

The electric push rod 10 is fixedly installed at the position close to the middle of the top of the bottom plate 1, and the surface of the electric push rod 10 is movably connected with a lifting frame 11. The number of lifting frames 11 is at least two groups, and each group of lifting frames Gaskets are pressed together at the connection positions of 11, as shown in Figure 4, since the electric push rod 10 and the elevator frame 11 need to be used repeatedly, the installation of gaskets effectively reduces the vertical movement of the elevator frame 11 when it is working The resulting wear and tear, thereby improving the service life of lifting frame 11;

The support plate 12, the top of the electric push rod 10 is fixedly connected with the support plate 12, and the four side outer walls of the support plate 12 are all built with a protective fence 13, and one side outer wall of the protective fence 13 is hinged with a protective door 14 , the bottom of the protective fence 13 is set against the top of the stairs 3, as shown in Figure 3, because the protective fence 13 has a certain height difference from the base plate 1, the setting of the bottom of the protective fence 13 and the top of the stairs 3 is convenient. The staff reaches the top of the support plate 12 through the stairs 3;

One side outer wall of the protective fence 13 is fixedly connected with a reel 15 by bolts, and the inside of the reel 15 is wound with a reinforcement rope 16, and the bottom end of the reinforcement rope 16 is connected with a tool box 17 through a rope buckle, and the reel 15 One side of the outer wall is installed with a motor 18 that provides a power source through the rotation of the rotating shaft. According to the accompanying drawing 1, because the staff needs to take tools back and forth when carrying out road and bridge construction work, running up and down will affect work efficiency. The motor 18 is installed on the outer wall of one side of the disk 15 so that the staff can activate the motor 18 according to the needs. Under the support of the power, the rotation of the reinforcement rope 16 drives the tool box 17 to move, thus facilitating the staff to take tools at high places .

Working principle: Before the electric push rod 10 is usually put into use, the staff holds the push handle 2 to move the electric push rod 10 as a whole to the place where road and bridge maintenance or construction is required, and then holds the hinge plate 8 to rotate and open, and takes out the support frame 7 and inserts it inside. At this time, according to the height difference between the bottom plate 1 and the ground, the staff holds multiple sets of support soil nails 9, and drives the support soil nails 9 into the ground in a spiral manner until they reach below the ground. The soil nails 9 are inserted below the ground, effectively supporting and stabilizing, and strengthening the overall stability of the supporting bracket to a certain extent;

When the height of the support plate 12 needs to be adjusted, the staff controls the lifting of the electric push rod 10, and the rise or fall of the electric push rod 10 drives the lifting frame 11 connected to its surface to move up and down, thus enhancing the stability of the electric push rod 10 until reaching a suitable height, the staff stops the movement of the electric push rod 10;

When the worker needs to take the tool, the hand-held motor 18 is started. At this time, the rotating shaft connected to one end of the motor 18 starts to rotate, driving the reinforcing rope 16 wound and stored inside the rotating reel 15 to rotate. Under the action of friction, the reinforcing rope 16 The tool box 17 that the bottom is connected moves up and down together, and the staff can move up and down the reinforcement rope 16 according to demand, thereby facilitates the taking of tool, above is the whole operating principle of the present utility model.

It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, no matter from all points of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, so it is intended to fall within the scope of the claims All changes within the meaning and range of equivalents of the required elements are included in the present invention. Any reference sign in a claim should not be construed as limiting the claim concerned.
