Description

A movable axle load scale

technical field

The utility model relates to the technical field of weighing equipment, in particular to a movable axle load scale.

Background technique

In the toll collection system of expressway toll stations, axle load scales are widely used, which have the advantages of high weighing efficiency, low equipment cost and small construction volume. The axle load scale includes a weighing platform, a frame, and a load cell. When in use, the frame needs to be poured on the ground with concrete. The upper surface of the frame is flush with the ground. Level with the ground.

During the use of the axle load scale, debris such as leaves and dust will fall into the gap between the weighing platform and the frame. Over time, these debris will accumulate too high and come into contact with the weighing platform, seriously affecting the weighing accuracy and stability. Therefore, the existing axle load scales need to be cleaned regularly every year. When cleaning, first rent a crane or forklift to lift the weighing platform from the frame, then use a shovel to clean up the sundries, and finally put the weighing platform back with a crane or forklift. The cost of renting a crane or forklift is relatively high. Toll booths, cranes or forklifts will be difficult to rent and will affect the progress of clean-up work.

Detailed ways

In order to make the purpose, technical solutions and advantages of the present utility model more clearly understood, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

As shown in FIG. 1 and FIG. 2 , the utility model provides a movable axle load scale, including: an axle load scale body 100 and a lifting caster assembly 200 .

The axle load scale body 100 includes a frame 110 installed in the ground pit, a weighing platform 120 arranged in the frame 110, and a load cell (not shown in the figure) arranged in the frame 110 and used to support the weighing platform 120 ).

As shown in Figure 4, the lifting caster assembly 200 includes a lifting rod 210 and a universal wheel 220; the lifting rod 210 includes a screw rod 211 connected to the universal wheel 220 at one end, A nut 212 , a threaded block 213 forming a screw nut pair with the screw rod 211 , and a support frame 214 connecting the threaded block 213 and the axle load scale body 100 .

In the movable axle load scale provided by this solution, the axle load scale body 100 and the lifting caster assembly 200 are preferably detachably connected. expressway toll station), and the lifting caster assembly 200 can be stored; connected to the weighing platform 120 of the screw rod 211, use a tool such as a wrench to apply force to the nut 212 fixed on the screw rod 211, so that the screw rod 211 rotates axially, thereby driving the threaded block 213 to rise along the axial direction of the screw rod 211, and then the weighing platform 120 Lift it up, as shown in Figure 2. When the bottom side of the weighing platform 120 is 300 above the ground, push the weighing platform 120 to move it away from the range of the frame 110. At this time, the debris in the frame 110 can be easily cleaned, and the weighing platform 120 is pushed back to the top of the frame 110 after cleaning. , screw the screw mandrel 211 to load the weighing platform 120 into the frame 110, and complete the whole cleaning operation.

Wherein, the nut 212 affixed to the screw mandrel 211 can be a commonly used type of nut such as a square nut or a hexagonal nut, and can be fixed on the end of the screw mandrel 211 by welding; it can also be directly processed at the end of the screw mandrel 211 The square or hexagonal structure is convenient for common tools such as wrenches to cooperate; of course, it can also be a handle fixedly connected to the end of the screw rod 211, and the rotation of the screw rod 211 can be achieved by directly applying force by hand.

In order to realize the connection between the supporting frame 214 of the lifting caster assembly 200 and the weighing platform 120, a specific solution is proposed: as shown in Figure 3, connecting holes 121 are provided on both sides of the weighing platform 120, and one end of the supporting frame 214 It is detachably connected with the connecting hole 121 . The connection hole 121 can be a counterbore, or a through hole. In order to improve the stability of the support frame 214 when supporting the weighing platform 120, the through hole can be a rectangular long hole, and the support frame 214 is adaptable. The choice of elongated hook structure.

A specific solution is proposed for the support frame: please refer to FIG. 4 again, the support frame 214 includes a support frame main body 214a, a reinforcing rib 214b and a hook structure 214c, the support frame main body 214a is in an inverted L shape, and its The horizontal part is fixedly connected to the threaded block 213, and the vertical part is connected to the hook structure 214c. The reinforcing rib 214b has two connecting sides, and the two connecting sides are respectively connected to the horizontal part and the horizontal part of the support frame main body 214a. vertical part. Wherein, the support frame main body 214a can be welded with the threaded block 213, or both can be integrally formed, and a bearing can also be arranged between the support frame main body 214a and the threaded block 213, to overcome the rotational movement generated when the threaded block 213 moves along the screw rod .

To make the reinforcing rib 214b have sufficient strength, a specific solution is proposed: please refer to FIG. 4 again, the outer contour 214b1 of the two connecting sides of the reinforcing rib 214b is in the shape of an L that is compatible with the main body 214a of the support frame. The inner contour line 214b2 of the two connecting sides of the reinforcing rib 214b includes two side lines 214b2a forming an obtuse angle, and a C-shaped transition line 214b2b located at the junction of the two side lines 214b2a. In this way, the bending part in the middle of the reinforcing rib 214b is thick enough, that is, the strength is sufficient, and the distal ends on both sides of the reinforcing rib 214b are relatively thin, which facilitates the installation of other components.

In order to facilitate the installation and maintenance of the universal wheel 220, a specific solution is proposed: please refer to FIG. The caster mounting plate 215 of the wheel 220, the universal wheel 220 can be connected with the caster mounting plate 215 in a threaded manner.

The specific embodiments of the utility model described above do not constitute a limitation to the protection scope of the utility model. Any other corresponding changes and deformations made according to the technical concept of the utility model shall be included in the protection scope of the claims of the utility model.
