Description

Technical Field

[0001] This utility model relates to a vacuum cleaner cart, specifically a vacuum cleaner cart with a lifting side suction cup. Background Technology

[0002] When a vacuum truck is operating at high speed, most of the foreign objects to be collected are concentrated within a certain distance outside the vehicle body (i.e., inside the road green belt or inside the curb). Because of the large number of foreign objects to be collected, the pressure of vacuuming the sides of the vacuum truck will be further increased. Therefore, relying solely on the main vacuum system in the center of the lower part of the vehicle body for vacuuming is inefficient, and additional auxiliary vacuum components are needed to supplement the function of the main vacuum system.

[0003] Side suction cups are a commonly used auxiliary vacuuming component in the industry. The side brush of a vacuum truck sweeps foreign objects within a certain distance from the outside of the truck body into the area under the side suction cup, where they are sucked into the truck body, thus collecting foreign objects from the sides. However, existing side suction cups are usually quite large, and the side brush and suction cup cannot be fully accommodated on the lower side of the truck body, leaving part of the suction cup exposed and susceptible to scratches and damage. Utility Model Content

[0004] The main purpose of this utility model is to solve the technical problem that the lower part of the existing vacuum truck body cannot fully accommodate the existing large side suction cups, resulting in the side suction cups being partially exposed outside the vehicle body and easily subject to scratches and damage. The present invention provides a vacuum truck with lifting side suction cups.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A vacuum cleaner truck with a lifting side suction cup includes a vehicle body, a sub-beam and a main beam disposed on the vehicle body, with the sub-beam located above the main beam; its special feature is that it also includes a lifting side suction cup disposed on the outside of the main beam and the sub-beam.

[0007] The lifting side suction cup includes a lifting cylinder hinged to the outer wall of the sub-beam, a mounting frame hinged to the output end of the lifting cylinder, a suction cup located on the lower side of the mounting frame, and a guide mechanism fixed to the outer walls of the main beam and the sub-beam.

[0008] The guiding mechanism includes two guide plates and four sets of guide pulleys. The two guide plates are located on the front and rear sides of the mounting frame, respectively, and are fixedly connected to the main beam and sub-beam on one side of the vehicle body. Each guide plate has two longitudinally extending guide grooves. Of the four sets of guide pulleys, the two sets of guide pulleys on the front side are respectively set in the two guide grooves on the front side, and the two sets of guide pulleys on the rear side are respectively set in the two guide grooves on the rear side. All four sets of guide pulleys are fixedly connected to the mounting frame and are used to guide the longitudinal movement of the mounting frame.

[0009] The suction cup is mounted on the underside of the mounting frame via four sets of fine-tuning mechanisms, which are used to adjust the distance between the front and rear sides of the suction cup and the ground.

[0010] Furthermore, each of the aforementioned fine-tuning mechanisms includes a chain and adjusting bolts. Of the four adjusting bolts, two are threadedly connected to the front end of the mounting bracket near both sides, and the other two are threadedly connected to the rear end of the mounting bracket near both sides. The upper end of the chain is connected to the adjusting bolts, and the lower end is fixed to the suction cup. The distance between the front and rear sides of the suction cup and the ground can be adjusted by the four adjusting bolts.

[0011] Furthermore, each set of the fine-tuning mechanism also includes a pin, the adjusting bolt is a hollow bolt, the upper end of the chain passes through the adjusting bolt and is connected to the adjusting bolt by the pin.

[0012] Furthermore, when the distance between the front and rear sides of the suction cup and the ground is adjusted by four fine-tuning mechanisms, the distance from the ground of the lower edge of the front side of the suction cup is defined as n1, and the distance from the ground of the lower edge of the rear side is defined as n2. Then, n1 > n2, and n2 = 5~15mm.

[0013] Furthermore, each chain has multiple links; the adjustment range of each adjusting bolt is less than the length of the chain link.

[0014] Furthermore, the suction cup is provided with an auxiliary wheel for providing cushioning on its rear sidewall, and the lower rim of the auxiliary wheel is in contact with the ground.

[0015] Furthermore, multiple support rods of equal length are provided between the two guide plates to provide lateral support for the guide plates and prevent the guide plates from deforming due to the tension of the mounting frame.

[0016] Furthermore, each set of guide pulleys includes two longitudinally arranged pulleys; let the maximum distance the mounting bracket moves longitudinally on the guide plate be N, the length of the guide groove be m, the distance between the centers of the two pulleys be k, and the diameter of each pulley be d, then N < m - (k + d).

[0017] Furthermore, each of the guide plates is provided with a limiting bolt on its side near the mounting bracket, and the limiting bolt is mounted on the guide plate through the mounting plate; when the mounting bracket is adjusted to the maximum distance N, its upper surface abuts against the end of the limiting bolt, thereby further limiting the mounting bracket.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model provides a vacuum cleaner with a lifting side suction cup. In the lifting side suction cup, the mounting bracket is directly hinged to the output end of the lifting cylinder. The lifting and lowering are directly adjusted by the extension and retraction of the lifting cylinder and the guidance of the guiding mechanism, thereby minimizing the lateral width of the lifting side suction cup so that it can adapt to the small installation space under the vacuum cleaner body.

[0020] 2. The present invention provides a vacuum cleaner with a lifting side suction cup. A fine-tuning mechanism is set between the suction cup and the mounting frame to adjust the distance between the front and rear sides of the suction cup and the ground. An auxiliary wheel is set to provide a buffer for the suction cup, thereby avoiding the suction cup from bottoming out due to uneven road surface, which would affect the normal operation of the vacuum cleaner.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] A vacuum cleaner with lifting side suction cups includes a vehicle body, a sub-beam 1 and a main beam 2 disposed on the vehicle body, wherein the sub-beam 1 is located above the main beam 2, and lifting side suction cups disposed on the outer side walls of the main beam 2 and the sub-beam 1.

[0028] The specific structure of the lifting side suction cup is as follows: Figure 1 As shown, it includes a lifting cylinder 3 hinged to the outer wall of the sub-beam 1, a mounting bracket 6 hinged to the output end of the lifting cylinder 3, a suction cup 7 located on the lower side of the mounting bracket 6, and a guide mechanism 4 fixed to the outer walls of the main beam 2 and the sub-beam 1.

[0029] The guiding mechanism 4 includes two guide plates 41 and four sets of guide pulleys 42, each set of guide pulleys 42 including two longitudinally arranged pulleys; the two guide plates 41 with weight-reducing holes are located on the front and rear sides of the mounting frame 6 respectively, and are both fixedly connected to the main beam 2 and sub-beam 1 on one side of the vehicle body; each guide plate 41 has two longitudinally extending guide grooves 43; of the four sets of guide pulleys 42, the two sets of guide pulleys 42 on the front side are respectively set in the two guide grooves 43 on the front side, and the two sets of guide pulleys 42 on the rear side are respectively set in the two guide grooves 43 on the rear side; all four sets of guide pulleys 42 are fixedly connected to the mounting frame 6; during the adjustment process, the lifting cylinder 3 pushes the mounting frame 6, causing it to move longitudinally under the guidance of the guide pulleys 42 and guide grooves 43, thereby realizing the height adjustment of the suction cup 7;

[0030] The suction cup 7 is mounted on the lower side of the mounting frame 6 via four sets of fine-tuning mechanisms 9. An auxiliary wheel 5 is mounted on the rear side wall of the suction cup 7, with the lower rim of the auxiliary wheel 5 in contact with the ground. The specific structure of the fine-tuning mechanism 9 is as follows: Figure 2 , Figure 3 As shown, the mounting bracket 6 includes a chain 91, adjusting bolts 92, and pins 93. All four adjusting bolts 92 are hollow bolts, with two threaded connections to the front end of the mounting bracket 6 near both sides, and the other two threaded connections to the rear end of the mounting bracket 6 near both sides. Each chain 91 has multiple links. The upper end of each chain 91 passes through the adjusting bolts 92 and is connected to the adjusting bolts 92 via pins 93, while the lower end is fixed to the suction cup 7. The distance between the front and rear sides of the suction cup 7 and the ground can be adjusted using the four adjusting bolts 92, and the adjustment range of each adjusting bolt 92 is less than the length of a chain link.

[0031] In this embodiment, the distance from the ground of the lower front edge of the suction cup 7 is n1, and the distance from the ground of the lower rear edge of the suction cup 7 is n2. During assembly, the adjusting bolt 92 needs to be turned to adjust n1 > n2 and n2 = 15mm. At this time, the two chains 91 located on the front side of the suction cup 7 are in a taut state, thereby lifting the front part of the suction cup 7. The two chains 91 located on the rear side of the suction cup 7 are in a relaxed state under the support of the auxiliary wheel 5. During the operation of the vacuum cleaner, the mounting frame 6 is located at the lowest point. If the ground protrudes, the upward design of the front side of the suction cup 7 can prevent it from hitting the bottom. When the vehicle drives over the protruding part of the ground, the auxiliary wheel 5 located on the rear side wall of the suction cup 7 provides a buffer for the suction cup 7, thereby keeping the distance between the suction cup 7 and the ground relatively constant during operation.

[0032] In addition, four support rods 8 of equal length are provided between the two guide plates 41 to provide lateral support for the guide plates 41, avoid deformation of the guide plates 41 due to the tension of the mounting frame 6, and further ensure smooth adjustment of the mounting frame 6; let the maximum distance of the mounting frame 6 moving longitudinally on the guide plate 41 be N, the length of the guide groove 43 be m, the distance between the centers of the two pulleys in each set of guide pulleys 42 be k, and the diameter of each pulley be d, then N≤m-(k+d); when N<m-(k+d), a limiting bolt 10 is provided on the side wall of each guide plate 41 near the mounting frame 6, the limiting bolt 10 is installed on the mounting plate and is installed on the guide plate 41 through the mounting plate; when the mounting frame 6 is adjusted to the maximum distance N, its upper surface abuts against the end of the limiting bolt 10, thereby further limiting the mounting frame 6 and preventing it from shaking during vehicle movement.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. For those skilled in the art, modifications can be made to the specific technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. However, these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions protected by this utility model.
