An automatic tarpaulin covering device

Abstract

This utility model discloses an automatic tarpaulin covering device, including a vehicle body. A fixing plate is bolted to one side of the outer surface of the vehicle body, and a roller is rotatably connected to the inner side wall of the fixing plate. This automatic tarpaulin covering device, through the arrangement of the roller, tarpaulin, support rod, and elastic rope, operates by first starting a motor to rotate the roller, allowing the tarpaulin to be rolled up onto the roller surface. Simultaneously, the support rod and rotating seat rotate, causing one end of the tarpaulin to pull the support rod to flip during the rolling process. At this time, the elastic rope is stretched by force until the tarpaulin is completely rolled up and the motor stops. The motor can be stopped by braking the motor after power is cut off. After the goods are loaded into the cargo compartment, the motor can be started to reverse the roller. The elastic rope's restoring action pulls the support rod to one side to flip, keeping the tarpaulin taut at all times. The device stops when the tarpaulin completely covers the truck, thus providing an automatic covering function that is easy to operate.

Description

Technical Field

[0001] This utility model relates to the field of tarpaulin application technology, and in particular to an automatic tarpaulin covering device. Background Technology

[0002] In recent years, with urban construction and development and the comprehensive utilization of land, dump trucks have been shuttling on city roads, causing great damage to the urban environment and people's lives. Therefore, all existing dump trucks are equipped with tarpaulin covering devices to cover and prevent the construction waste from spilling and flying.

[0003] Currently, most tarpaulins on dump trucks are laid manually, lacking an automatic laying function, which makes operation cumbersome. Furthermore, current tarpaulin covering devices do not have the effect of cleaning the tarpaulin. Since the tarpaulin is exposed to the natural environment for a long time after being covered, dust easily settles on the surface. Manual cleaning is troublesome and inefficient. Therefore, it is necessary to design an automatic tarpaulin covering device. Utility Model Content

[0004] The main objective of this invention is to provide an automatic tarpaulin covering device that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An automatic tarpaulin covering device includes a vehicle body. A fixing plate is bolted to one side of the outer surface of the vehicle body. A roller is rotatably connected to the inner sidewall of the fixing plate. One end of the roller passes through the inner sidewall of the fixing plate and extends to the outer surface of the fixing plate. A tarpaulin is fixedly connected to one side of the outer surface of the roller. A motor is mounted on one side of the outer surface of the fixing plate, and the output end of the motor is fixedly connected to the roller. A rotating seat is fixedly connected to one side of the outer surface of the vehicle body. A support rod is rotatably connected to one side of the outer surface of the rotating seat. One end of the support rod is fixedly connected to the tarpaulin. An elastic rope is fixedly connected to one side of the outer surface of the vehicle body, and one end of the elastic rope is fixedly connected to the support rod.

[0007] In order to achieve a sliding effect, as an automatic tarpaulin covering device of this utility model, a vertical rod is fixedly connected to the lower surface of the fixing plate, and a sliding plate is slidably connected to the outer surface of the vertical rod.

[0008] In order to achieve a rebound effect, as an automatic tarpaulin covering device of this utility model, a spring is fixedly connected to the bottom end of the vertical rod, and a vertical plate is fixedly connected to the upper surface of the sliding plate.

[0009] In order to achieve a transmission effect, as an automatic tarpaulin covering device of this utility model, the inner side wall of the vertical plate is rotatably connected to a contact shaft, and the surface of the contact shaft is coated with a rubber layer.

[0010] In order to enable rotation, as an automatic tarpaulin covering device of this utility model, one end of the contact shaft penetrates the inner sidewall of the vertical plate and extends to the outer surface of the vertical plate, and one end of the contact shaft is fixedly connected with an active tooth.

[0011] In order to enable the driven shaft to rotate, as an automatic tarpaulin covering device of this utility model, the inner side wall of the vertical plate is rotatably connected to the driven shaft, and one end of the driven shaft is fixedly connected to the driven tooth.

[0012] In order to achieve a cleaning effect, as an automatic tarpaulin covering device of this utility model, the driven tooth and the driving tooth are meshed together, and the outer surface of the driven shaft is fixedly connected with bristles.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In this utility model, through the arrangement of a roller, tarpaulin, support rod, and elastic rope, during use, the motor is first started to drive the roller to rotate, so that the tarpaulin can be rolled up on the surface of the roller. At the same time, the support rod and the rotating seat have a rotating effect. During the rolling process, one end of the tarpaulin will pull the support rod to flip. At this time, the elastic rope is stretched by the force until the tarpaulin is completely rolled up and the motor is stopped. The motor can be stopped by braking the motor and locking it after power is cut off. After the goods are loaded into the bin, the motor can be started to drive the roller to reverse. The elastic rope restores the load and pulls the support rod to flip to one side, so that the tarpaulin is always in a taut state. When the tarpaulin completely covers the truck, it can be stopped, thus having an automatic covering function and convenient operation.

[0015] 2. In this utility model, through the arrangement of a sliding plate, a spring, a contact shaft, and a driven shaft, during use, the sliding plate has a sliding effect on the surface of the vertical rod, while the spring will always push the sliding plate, which facilitates the change in thickness after the tarpaulin is rolled up. This allows the contact shaft to contact the rolled-up tarpaulin. The roller drives the tarpaulin to roll up while simultaneously driving the contact shaft to rotate. Utilizing the meshing action of the driven teeth and the driving teeth, the rotation of the contact shaft will cause the driving teeth to rotate, thereby causing the driven shaft to rotate. The brush bristles scrape the surface of the tarpaulin, providing an automatic cleaning function and avoiding the trouble of manual cleaning. Furthermore, only concentrated maintenance and cleaning of the brush bristles are required in the later stages. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0023] like Figure 1-5 As shown, an automatic tarpaulin covering device includes a vehicle body 1. A fixing plate 2 is fixedly connected to one side of the outer surface of the vehicle body 1 by bolts. A roller 3 is rotatably connected to the inner side wall of the fixing plate 2. One end of the roller 3 passes through the inner side wall of the fixing plate 2 and extends to the outer surface of the fixing plate 2. A tarpaulin 4 is fixedly connected to one side of the outer surface of the roller 3. A motor 5 is installed on one side of the outer surface of the fixing plate 2. The output end of the motor 5 is fixedly connected to the roller 3.

[0024] In this embodiment, a rotating seat 6 is fixedly connected to one side of the outer surface of the vehicle body 1, and a support rod 7 is rotatably connected to one side of the outer surface of the rotating seat 6. One end of the support rod 7 is fixedly connected to the tarpaulin 4, and an elastic rope 8 is fixedly connected to one side of the outer surface of the vehicle body 1. One end of the elastic rope 8 is fixedly connected to the support rod 7.

[0025] In practical use, first start motor 5 to drive roller 3 to rotate, so that tarpaulin 4 can be rolled up on the surface of roller 3. At the same time, the support rod 7 and the rotating seat 6 have a rotating effect. During the rolling process, one end of tarpaulin 4 will pull the support rod 7 to flip. At this time, the elastic rope 8 is stretched by the force until tarpaulin 4 is completely rolled up and motor 5 is stopped. Motor 5 can be locked after the brake motor is de-energized. After the goods are loaded into the bin, motor 5 can be started to drive roller 3 to reverse. The elastic rope 8 restores its effect and pulls the support rod 7 to flip to one side, so that tarpaulin 4 is always in a taut state. When tarpaulin 4 completely covers the truck, it can be stopped, thus having an automatic covering function and convenient operation.

[0026] In this embodiment, a vertical rod 9 is fixedly connected to the lower surface of the fixing plate 2, and a sliding plate 10 is slidably connected to the outer surface of the vertical rod 9.

[0027] In practical use, the slide plate 10 slides on the vertical bar 9, allowing the slide plate 10 to slide up and down.

[0028] In this embodiment, a spring 11 is fixedly connected to the bottom end of the vertical rod 9, and a vertical plate 12 is fixedly connected to the upper surface of the slide plate 10.

[0029] In practical use, the spring 11 pushes the slide plate 10 so that the slide plate 10 is always subjected to force, so that the height of the slide plate 10 can be automatically adjusted while the tarpaulin 4 is unfolded and rolled up.

[0030] In this embodiment, a contact shaft 13 is rotatably connected to the inner sidewall of the vertical plate 12, and the surface of the contact shaft 13 is coated with a rubber layer.

[0031] In practical use, the rubber coating on the surface of the contact shaft 13 increases the friction. After the contact shaft 13 contacts the surface of the tarpaulin 4, when the tarpaulin 4 is rolled up or unfolded, it can drive the contact shaft 13 to rotate. The force of the elastic rope 8 is greater than that of the spring 11, which facilitates the rebound of the elastic rope 8. The force of the spring 11 is greater than the friction between the contact shaft 13 and the tarpaulin 4, which ensures that the contact shaft 13 is always in contact and can transmit normally.

[0032] In this embodiment, one end of the contact shaft 13 penetrates the inner sidewall of the vertical plate 12 and extends to the outer surface of the vertical plate 12, and one end of the contact shaft 13 is fixedly connected to the active tooth 14.

[0033] In practical use, the roller 3 drives the tarpaulin 4 to roll up while simultaneously driving the contact shaft 13 to rotate, causing the drive gear 14 to rotate under the applied force.

[0034] In this embodiment, a driven shaft 15 is rotatably connected to the inner sidewall of the vertical plate 12, and a driven tooth 16 is fixedly connected to one end of the driven shaft 15.

[0035] In practical use, the meshing action between the driven tooth 16 and the driving tooth 14 will cause the driving tooth 14 to rotate after the contact shaft 13 rotates.

[0036] In this embodiment, the driven tooth 16 is meshed with the driving tooth 14, and the outer surface of the driven shaft 15 is fixedly connected with bristles 17.

[0037] In practical use, the active tooth 14 drives the driven tooth 16 to rotate, thereby causing the driven shaft 15 to rotate, and the bristles 17 are used to scrape the surface of the tarpaulin 4.

[0038] Working principle: During use, motor 5 is first started to drive roller 3 to rotate, allowing tarpaulin 4 to be rolled up on the surface of roller 3. Simultaneously, the support rod 7 and rotating seat 6 rotate, causing one end of tarpaulin 4 to pull the support rod 7 to flip during the rolling process. At this time, the elastic rope 8 is stretched by the force until tarpaulin 4 is completely rolled up and motor 5 is stopped. Motor 5 can be locked after the brake motor is de-energized. After the goods are loaded into the cargo compartment, motor 5 can be started to drive roller 3 to reverse. The elastic rope 8 then recovers, pulling the support rod 7 to flip to one side, keeping tarpaulin 4 taut at all times. The process stops when tarpaulin 4 completely covers the truck, thus providing automatic covering. The cover is easy to operate. The sliding plate 10 slides on the surface of the vertical rod 9, and the spring 11 will always push the sliding plate 10 to facilitate the thickness change of the tarpaulin 4 after it is rolled up. This allows the contact shaft 13 to contact the rolled-up tarpaulin 4. The roller 3 drives the tarpaulin 4 to roll up and drives the contact shaft 13 to rotate. Utilizing the meshing of the driven tooth 16 and the driving tooth 14, the rotation of the contact shaft 13 will cause the driving tooth 14 to drive the driven tooth 16 to rotate, thereby causing the driven shaft 15 to rotate. The brush bristles 17 scrape the surface of the tarpaulin 4, which has an automatic cleaning function, avoiding the trouble of manual cleaning. Moreover, only the brush bristles 17 need to be maintained and cleaned in the later stage.
