[0001] This utility model relates to the field of building construction, and in particular to a weighbridge structure for building construction sites. Background Technology

[0002] During construction, it is usually necessary to set up a weighbridge on the construction site to weigh concrete, steel bars, and turnover materials. Currently, due to the limited space of the construction site, the application of shallow foundation pit weighbridges is becoming increasingly widespread.

[0003] During the construction of shallow pit weighbridges, a long, narrow pit is usually excavated first, and then the weighbridge is embedded in the pit. For ease of maintenance, an inspection hole is typically installed at the sensor location of the weighbridge, and a cover plate is installed at the opening to ensure that vehicles can pass through the inspection hole area normally.

[0004] However, the most common type of cover plate currently used is a concrete cover plate. Large vehicles are prone to collapse or overturning when passing over the cover plate. In addition, concrete cover plates are heavy and easily damaged during transportation, which is not conducive to the maintenance of sensors. Therefore, improvements are needed. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a weighbridge structure for construction sites that can prevent the cover plate from collapsing or overturning, ensure the normal passage of vehicles, and at the same time enable convenient removal and removal of the cover plate and convenient maintenance of the sensor.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a weighbridge structure for a construction site, comprising: The foundation pit itself is long and narrow; A load-bearing platform is horizontally set on the ground of the foundation pit body; The weighbridge body is arranged on the load-bearing platform; The inspection port is connected to the foundation pit body and is located at the top corner of the weighbridge body; A protective cover is provided to cover the access port. The protective cover includes a support frame, columns, sliding rods, and a cover plate. The support frame is horizontally arranged on the bottom surface of the inspection port. The columns are vertically arranged at the four corners of the support frame. The sliding rods are vertically slidably connected to the columns. The upper end of the columns is provided with a locking pin for inserting the sliding rods. The cover plate is horizontally arranged on the upper end of the multiple sliding rods and covers the inspection port.

[0007] In a preferred embodiment, the present invention can be further configured such that: the upper end of the inspection port is provided with a groove for the edge of the cover plate to be embedded.

[0008] In a preferred embodiment, the present invention can be further configured such that angle steel frames are embedded at the edges of both the foundation pit body and the inspection port.

[0009] In a preferred embodiment, the present invention can be further configured such that a pair of lifting holes are provided on the cover plate.

[0010] In a preferred embodiment, the present invention can be further configured such that each of the four corners of the support frame is threaded with a leveling support foot.

[0011] In a preferred embodiment, the present invention can be further configured such that a drainage ditch is provided between the load-bearing platform and the inner side of the foundation pit body.

[0012] In a preferred embodiment, the present invention can be further configured such that: a water distributor is provided on the support frame and placed on the ground of the inspection port, and a suction pipe is provided on the water distributor.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings.

[0018] like Figure 1 , Figure 2 , Figure 3 As shown, a weighbridge structure for a construction site includes a foundation pit body 1, a load-bearing platform 2, a weighbridge body 3, an inspection port 4, and a protective cover 5.

[0019] like Figure 1 , Figure 2 As shown, the foundation pit body 1 is elongated, the support platform 2 is horizontally positioned on the ground of the foundation pit body 1, and the weighbridge body 3 is arranged on the support platform 2. The inspection port 4 is connected to the foundation pit body 1 and is located at the top corner of the weighbridge body 3.

[0020] like Figure 1 , Figure 2 As shown, the upper end of the inspection port 4 is provided with a groove 41, and the edge of the protective cover 5 is embedded in the groove 41 and is used to cover the inspection port 4.

[0021] like Figure 2 , Figure 3 As shown, the protective cover 5 includes a support frame 51, a column 52, a sliding rod 53, and a cover plate 54. The support frame 51 is horizontally set on the bottom surface of the inspection port 4. Each of the four corners of the support frame 51 is threaded with a leveling foot 55 to adjust the level of the support frame 51 and ensure its stability.

[0022] like Figure 2 , Figure 3 As shown, the columns 52 are vertically installed at the four corners of the support frame 51, and the sliding rods 53 are vertically slidably connected to the columns 52. The upper end of the columns 52 is provided with locking pins 56 for inserting the sliding rods 53. The cover plate 54 is horizontally installed above the multiple sliding rods 53 and covers the inspection port 4. The cover plate 54 is provided with a pair of lifting holes 57 to realize convenient lifting and hoisting of the cover plate 54.

[0023] When it is necessary to inspect the sensors on the weighbridge body 3, insert a hook or tool into the lifting hole 57 on the cover plate 54, and then control the cover plate 54 to move the sliding rod 53 upward, opening the inspection port 4. Then, insert the locking pin 56 into the sliding rod 53 to fix the sliding rod 53 and the cover plate 54, at which point the sensor can be repaired. In actual work, the entire protective cover 5 can also be lifted, so that the protective cover 5 is completely removed from the inspection port 4, and then workers can enter the inspection port 4 for inspection. Both methods can meet the needs of sensor maintenance and ensure the normal operation of the weighbridge.

[0024] After maintenance is completed, the entire protective cover 5 can be hoisted into the access port 4. Then, adjust and level the support legs 55 to ensure that the support frame 51 is stably placed inside the access port 4. Next, pull out the locking pin 56 and slowly move the cover plate 54 downwards, causing the sliding rod 53 to retract into the column 52. Until the cover plate 54 is embedded in the groove 41 on the access port 4, the sliding rod 53 is fully retracted into the column 52, allowing the column 52 to support the cover plate 54, which then allows vehicles to pass through.

[0025] Therefore, by covering the inspection port 4 with a steel cover plate 54 and installing a telescopic support component below the cover plate 54, the load-bearing capacity of the protective cover 5 is improved, preventing the protective cover 5 from collapsing or overturning, ensuring the normal passage of vehicles. At the same time, the telescopic support component can lift the cover plate 54, enabling convenient inspection and maintenance of the sensor.

[0026] like Figure 1 , Figure 2 As shown, angle steel frames 6 are embedded at the edges of the pit body 1 and the inspection port 4 to protect the edges, prevent cracking or damage when vehicles run over them, and ensure the service life of the weighbridge structure.

[0027] like Figure 2 , Figure 3 As shown, a drainage ditch 7 is provided between the inner side of the support platform 2 and the foundation pit body 1. A water distributor 8 is provided on the support frame 51 and placed on the ground of the inspection port 4. A suction pipe 81 is provided on the water distributor 8.

[0028] like Figure 2 , Figure 3 As shown, a long strip-shaped mounting hole 9 is provided on one side of the cover plate 54. A mounting plate 91 is rotatably connected inside the mounting hole 9. A clamp 92 for fixing the suction tube 81 is provided at the lower end of the mounting plate 91.

[0029] When rainfall occurs, rainwater can collect in the drainage ditch 7 formed between the inner side of the load-bearing platform 2 and the foundation pit body 1, and then the rainwater enters the inspection port 4 for storage. After the rainfall ends, the control mounting plate 91 is flipped outward, causing the mounting plate 91 to drive the suction pipe 81 out. Then, the water pump is connected to the suction pipe 81, and in conjunction with the water distributor 8, the water accumulated in the inspection port 4 is promptly sucked out and conveniently discharged, thereby ensuring the normal operation of the weighbridge.
