Description
Technical Field
[0001] The utility model relates to the technical field of Cistanche deserticola processing, in particular to a device for detecting the bearing capacity of a simulated municipal highway bridge. Background Art
[0002] Highway bridge projects include the main body of the bridge (i.e. the bridge superstructure and the bridge substructure) and the ancillary engineering facilities in the bridge as a whole. Therefore, before construction, it is often necessary to measure the bearing capacity of the road bridge to limit the final bearing capacity and reduce the occurrence of accidents.
[0003] At present, some highway bridge bearing capacity detection devices often use tools such as drill rods to measure the bridge body after the bridge is formed. This method is likely to cause damage to the formed bridge module, thus affecting normal use. At the same time, when the bearing capacity of the bridge module cannot meet the requirements, it is easy to cause the pre-made bridge module to be unusable and need to be reworked, which increases the workload of the pre-construction. Therefore, it is necessary to propose a road bridge measurement device that is easy to use. Utility Model Content

This method is likely to cause damage to the formed road bridge module, thereby affecting normal use. At the same time, when the bearing capacity of the road bridge module cannot meet the requirements, it is easy to cause the road bridge module manufactured in the early stage to be unusable and need to be reworked, which increases the workload of the early construction.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a device for simulating the bearing capacity of a municipal highway bridge, comprising: a working frame; a sleeve, fixedly mounted on a side surface of the working frame; and further comprising:
[0006] Two U-shaped frames are fixedly mounted on the inner walls on opposite sides of the working frame, and one side surface of the two U-shaped frames is fixedly mounted with an anti-slip pad;

[0009] Preferably, a connecting rod is fixedly mounted on a surface of the mounting plate on one side away from the hydraulic cylinder.
[0010] The technical effect of adopting the above further solution is that when the hydraulic cylinder is working, the mounting plate on the surface and the connected connecting rod are driven to move.
[0011] Preferably, a pressure block is fixedly mounted on the surface of the connecting rod away from the mounting plate, and the surfaces on the opposite sides of the sleeve are both provided with notches.
[0012] The technical effect of adopting the above further solution is that when the connecting rod moves, the pressure block on the surface is driven to move.
[0013] Preferably, guide rods are fixedly mounted on the inner walls of the two notches, and movable plates are movably sleeved on the outer surfaces of the two guide rods.
[0014] The technical effect of adopting the above further solution is: the guide rod is fixed by the notch, and at the same time the guide rod enables the movable plate to maintain a limited position when moving.
[0015] Preferably, one side surface of the movable plate is movably connected to the surface of the mounting plate, and springs are fixedly installed at opposite positions of the side surface of the movable plate away from the mounting plate.
[0016] The technical effect of adopting the above further solution is: when the mounting plate moves, the movable plate on the surface of the mounting plate is driven to move, and at the same time the spring is connected to the surface of the movable plate to provide a reset capability for the movable plate.

[0035] In this embodiment, when in use, the road and bridge template formed in proportion is placed on the surface of the anti-slip pad 108, and then the bolt 106 on the surface of the U-shaped frame 105 is rotated so that the positioning piece 107 on the surface of the positioning piece 107 fixes the road and bridge template. When the road and bridge template is placed, it slides when subjected to force, thereby affecting the measurement. When the hydraulic cylinder 205 power supply on the surface of the working frame 1 is connected, it works, driving the mounting plate 206, the connecting rod 207 and the pressing block 208 on the output end surface to move, and at the same time, the pressing block 208 contacts the road and bridge template and applies pressure until the road and bridge template breaks. One side surface of plate 206 is movably connected to the surface of movable plate 204, and movable plate 204 is embedded in the outer surface of guide rod 202, and the two ends of spring 203 are respectively connected to the surface of slot 201 and movable plate 204, thereby driving movable plate 204 to move, and scale lines are set on the surface of sleeve 2 to observe the moving distance, so as to calculate the pressure on the road and bridge template, and movable plate 204 has a reset function, which is convenient for multiple measurements, and when the measured data reaches the standard, the road and bridge manufacturing project is carried out by proportion, which improves the fault tolerance rate and reduces the construction period.
[0036] Embodiment 2: A connecting rod 207 is fixedly mounted on the surface of the mounting plate 206 away from the hydraulic cylinder 205, and a pressing block 208 is fixedly mounted on the surface of the connecting rod 207 away from the mounting plate 206. A notch 201 is provided on the surface of the sleeve 2 on the opposite side, and a guide rod 202 is fixedly mounted on the inner wall of the two notches 201. A movable plate 204 is movably sleeved on the outer surface of the two guide rods 202. A surface of one side of the movable plate 204 is movably connected to the surface of the mounting plate 206. The surface of the movable plate 204 on the opposite side of the surface of the one side away from the mounting plate 206 is Springs 203 are fixedly installed on both sides, and one end surfaces of the two springs 203 are fixedly installed on the inner wall of the slot 201.

[0037] In this embodiment, a limiting groove 101 is opened on the surface of the working frame 1. When the bidirectional screw rod 102 on the inner wall of the limiting groove 101 is rotated, the moving block 103 threadedly embedded on the outer surface of the bidirectional screw rod 102 is driven to move relative to it.

At the same time, the moving plate 204 is embedded in the outer surface of the guide rod 202, and the two ends of the spring 203 are respectively connected to the notch 201 and the surface of the moving plate 204, thereby driving the moving plate 204 to move, and setting the scale on the surface of the sleeve 2 line, so as to observe the moving distance, so as to calculate the pressure on the road and bridge template. At the same time, the movable plate 204 has a reset function, which is convenient for multiple measurements. When the measured data reaches the standard, the road and bridge production project is carried out through the proportion, which improves the fault tolerance rate and reduces the construction period. At the same time, a limit groove 101 is opened on the surface of the working frame 1. When the bidirectional screw rod 102 on the inner wall of the limit groove 101 is rotated, the moving block 103 threadedly embedded on the outer surface of the bidirectional screw rod 102 is driven to move relative to it. At the same time, the outer surface of the moving block 103 is slidably embedded on the inner wall of the limit groove 101 to prevent the moving block 103 from tilting when moving, and at the same time, the bridge support rod 104 on the surface is driven to move, and the road and bridge template is supported by the bridge support rod 104 to simulate the support point of the road and bridge. By adjusting the position of the support point, the bearing capacity of the road and bridge template is measured, so as to find a suitable support point, which is convenient for later construction.
