Description

Technical Field

[0001] The utility model belongs to the field of elevators, and particularly relates to an elevator for transporting cattle and sheep. Background Art

[0002] Using a single-story breeding shed to raise cattle and sheep (cattle and sheep refer to cattle or sheep) will occupy a relatively large land area. Due to the precious land resources, multi-story buildings are now widely used for centralized breeding of cattle and sheep. On the basis of the same breeding quantity, the land usage of multi-story buildings is less, which can reduce the land use cost of breeding enterprises.

[0003] When raising cattle and sheep in a multi-story building, when the cattle and sheep are ready for slaughter, an elevator is needed to transfer the cattle and sheep to the first floor. To improve work efficiency, generally, multiple cattle or multiple sheep are driven into the car and transported to the first floor together, and then loaded onto a vehicle and taken away. After multiple cattle and sheep are driven into the car, since the car is relatively crowded and cattle and sheep are disobedient, the cattle and sheep that enter the car and are close to the car door often stick out or even walk out of the car, which is sensed by the infrared anti-pinch device on the car door, causing the car door to be unable to close for a long time and making it difficult to quickly transport the cattle and sheep away. In the case where the car door cannot be closed in time, the elevator will also give an alarm, causing a series of troubles. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an elevator for transporting cattle and sheep. The utility model has the advantages of being able to improve the transportation speed of cattle and sheep and reduce elevator alarms.

[0006] In the aforementioned elevator for transporting cattle and sheep, a gap with a width less than 5 mm is formed between the turning plate assembly and the floor, and a baffle with one side fixed to the floor is provided above the gap.

[0007] In the aforementioned elevator for transporting cattle and sheep, the turning plate assembly includes a telescopic compensation plate and a rotating plate located on the same plane. The telescopic compensation plate is provided with a plurality of slots with a width less than 2 cm, a first rib plate vertically passing through all the slots is provided on the bottom surface of the telescopic compensation plate, the rotating plate is provided with a plurality of plug plates cooperating with the slots, a second rib plate connecting all the plug plates is provided on the bottom surface of the rotating plate, strengthening plates are provided on both long sides of the rotating plate, the strengthening plates are fixed to the bottom surface of the rotating plate, and both ends of the second rib plate are respectively fixed to the two strengthening plates.

[0008] In the aforesaid cattle and sheep transportation elevator, the rotating shaft between the two reinforcing plates is close to the floor, and the rotating shaft is rotatably connected to the bottom surface of the step groove through a bracket.

[0009] In the aforesaid cattle and sheep transportation elevator, there are two first rib plates and two second rib plates, and the two second rib plates are located between the two first rib plates.

[0010] In the aforesaid cattle and sheep transportation elevator, the rotating plate assembly further includes at least two guide posts. The guide posts pass through the first rib plate and the second rib plate, are slidably connected to the first rib plate, and are fixed to the second rib plate.

[0011] In the aforesaid cattle and sheep transportation elevator, the driving mechanism includes a motor fixed to the telescopic compensation plate. A screw rod is provided at the output end of the motor, and a nut fixed to the rotating plate is provided on the screw rod. An inclined connecting rod is provided below the nut. One end of the connecting rod is hinged to the nut, and the other end of the connecting rod is hinged to the bottom surface of the step groove.

[0012] In the aforesaid cattle and sheep transportation elevator, the connecting rod includes a front side rod connecting the bottom surface of the groove and a rear side rod connecting the nut. A guide hole is provided at the rear end of the front side rod, a compression spring is provided in the guide hole, a sliding pin fixed to the rear side rod is provided at the rear side of the compression spring, a pin shaft is provided in the radial direction of the sliding pin, both ends of the pin shaft extend out of the front side rod, and a long hole matched with the pin shaft is provided on the front side rod.

[0013] In the aforesaid cattle and sheep transportation elevator, the extension line of the connecting rod passes through below the rotating shaft, and a front support plate fixed to the bottom surface of the step groove is provided at the bottom of the front end of the rotating plate assembly; travel switches are provided on both the front and rear sides of the nut, and the motor and the travel switches are both connected to the controller.

[0014] Compared with the prior art, on the basis of the existing freight elevator, the present utility model improves the car. A step groove is provided at the front side of the car floor, and a rotating plate assembly is provided in the step groove. Usually, the rotating plate assembly is flush with the floor, creating a flat ground in the car to facilitate the transportation of goods. When cattle and sheep enter the car, the rotating plate assembly can rotate to create an inclined surface at the front side of the car floor where cattle and sheep cannot stand, fixing the activity range of the cattle and sheep in the car, preventing the cattle and sheep from sticking out or walking out of the car and not being sensed by the infrared anti-pinch device on the car door, enabling the car door to close in time, not only improving the transportation speed of cattle and sheep but also reducing a series of troubles caused by elevator alarms. Therefore, the present utility model has the advantages of being able to improve the transportation speed of cattle and sheep and reducing elevator alarms.

[0015] In addition, through further improvement, under the action of the driving mechanism, the rotating plate assembly can not only rotate, but also expand and contract to adjust the width of the cover plate, reducing the gap between the rotating plate assembly and the car door after flipping, preventing the hooves of cattle and sheep from getting stuck between the car door and the rotating plate assembly, avoiding injury to cattle and sheep, and having good safety. The driving mechanism adopts a single-motor drive, which can not only reduce costs but also reduce the difficulty of electric control.

[0016] The connecting rod is composed of front and rear side rods, and there is a compression spring between the front and rear side rods. When the rotating plate assembly is kept horizontal, since the extension line of the connecting rod passes under the rotating shaft, the compression spring gives the connecting rod a stress to become longer, thereby pushing the rotating plate assembly with a pressure to flip the front end downward, pressing the front end of the rotating plate assembly against the front support plate to prevent it from tilting, creating favorable conditions for pushing goods outside the car into the car.

[0017] The rotating plate assembly is composed of a rotating plate and a telescopic compensation plate. By setting rib plates on the rotating plate and the telescopic compensation plate, not only the structural strength of the rotating plate assembly is improved, the service life is extended, but also a limiting effect is achieved, enabling the rotating plate and the telescopic compensation plate to be well maintained in the same plane with each other, providing favorable support for creating a flat car floor.

Detailed Embodiments

[0026] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments, but it shall not be used as a basis for limiting the present utility model.

[0027] Embodiment. A cattle and sheep transportation elevator, as Figure 1 shown, the elevator includes a car, and a car door 1 is provided on the front side of the car. The feature is that a step groove is provided on the floor 2 of the car near the car door 1. The depth of the step groove is 15 cm. A turning plate assembly with a front end that can be turned upwards is provided in the step groove. The top surface of the turning plate assembly is flush with the floor 2 of the car, and a driving mechanism is provided on the turning plate assembly. A gap 3 with a width of 4 mm is formed between the turning plate assembly and the floor 2. A baffle 4 with one side fixed to the floor 2 is provided above the gap 3, and the baffle 4 is used to cover the gap 3. A front support plate 27 fixed to the bottom surface of the step groove is provided at the bottom of the front end of the turning plate assembly.

[0028] The turning plate assembly includes a telescopic compensation plate 5 and a rotating plate 6 located on the same plane. A plurality of slots 7 with a width less than 2 cm are provided on the telescopic compensation plate 5. Two first rib plates 8 vertically passing through all the slots 7 are provided on the bottom surface of the telescopic compensation plate 5. A plurality of plug plates 9 matching with the slots 7 are provided on the rotating plate 6. Two second rib plates 10 connecting all the plug plates 9 are provided on the bottom surface of the rotating plate 6. Reinforcing plates 11 are provided on both long sides of the rotating plate 6, and the reinforcing plates 11 are fixed to the bottom surface of the rotating plate 6. The two ends of the two second rib plates 10 are respectively fixed to the two reinforcing plates 11. The two second rib plates 10 are located between the two first rib plates 8

[0029] A rotating shaft 12 is provided between the two reinforcing plates 11. The rotating shaft 12 is close to the floor 2, and the rotating shaft 12 is rotatably connected to the bottom surface of the step groove through a bracket 13.

[0030] The turning plate assembly further includes two guide posts 14. The guide posts 14 pass through the first rib plate 8 and the second rib plate 10. The guide posts 14 are slidably connected to the first rib plate 8 and fixed to the second rib plate 10. In fact, when the width of the plug plate 9 is the same as the width of the slot 7, the guide posts do not need to be provided, because the first rib plate 8 and the second rib plate 10 have restricted the telescopic compensation plate 5 and the rotating plate 6 to be in the same plane. When the width of the plug plate 9 is the same as the width of the slot 7, the telescopic compensation plate 5 and the rotating plate 6 are also limited in the left-right direction. However, considering that when the width of the plug plate 9 is the same as the width of the slot 7, the telescopic compensation plate 5 and the rotating plate 6 are prone to jamming in the front-back direction. Therefore, it is preferred that the plug plate 9 and the slot 7 are in clearance fit, and the telescopic compensation plate 5 and the rotating plate 6 are limited in the left-right direction through the guide posts 14.

[0031] The driving mechanism includes a motor 15 fixed to the telescopic compensation plate 5. The motor 15 is fixed to the second rib plate 10 at the rear side. A screw rod 16 is provided at the output end of the motor 15. A nut 17 fixed to the rotating plate 6 is provided on the screw rod 16. An inclined connecting rod 18 is provided below the nut 17. One end of the connecting rod 18 is hinged to the nut 17, and the other end of the connecting rod 18 is hinged to the bottom surface of the stepped groove.

[0032] The connecting rod 18 includes a front rod 19 connecting the bottom surface of the groove and a rear rod 20 connecting the nut 17. A guiding hole 21 is provided at the rear end of the front rod 19. A compression spring 22 is provided in the guiding hole 21. A sliding pin 23 fixed to the rear rod 20 is provided at the rear side of the compression spring 22. The sliding pin 23 is matched with the guiding hole 21. A pin shaft 24 is provided in the radial direction of the sliding pin 23. Both ends of the pin shaft 24 extend out of the front rod 19. A long hole 25 matched with the pin shaft 24 is provided on the front rod 19.

[0033] The extension line of the connecting rod 18 passes through below the rotating shaft 12; travel switches 26 are provided on both the front and rear sides of the nut 17. The motor 15 and the travel switches 26 are both connected to a controller. The controller is preferably remotely controlled and includes a remote controller connected by wireless signal.

[0034] Usage method: Under normal conditions, the rotating plate assembly is horizontally arranged and flush with the floor 2, forming a flat ground inside the car. After driving the cattle and sheep into the car, a signal is sent to the controller through the remote controller. The controller starts the motor 15. The motor 15 makes the nut 17 move forward (towards the car door 1). The nut 17 drives the telescopic compensation plate 5 to move away from the rotating plate 6, and at the same time drives the rear end of the connecting rod 18 to rotate upward. Under the action of the connecting rod 18, the front end of the rotating plate 6 turns upward, forming an inclined surface on the rotating plate assembly. The cattle and sheep cannot stand on the inclined surface and can only move backward, away from the car door, so as to avoid being sensed by the infrared anti-pinch device on the car door, enabling the car door to close smoothly. When the nut 17 moves to touch the travel switch 26 on the front side, the controller stops the motor 15. At this time, after the car door is closed, the gap left between the telescopic compensation plate 5 and the car door should be less than 5 mm (the width of the gap can be different by using screw rods 16 with different pitches), to avoid the hooves of the cattle and sheep getting stuck in it.

[0035] When the car reaches the corresponding floor and the car door is opened, a signal is sent to the controller through the remote controller. The controller starts the motor 15. The motor 15 makes the nut 17 move backward until the nut 17 touches the travel switch 26 on the rear side, and the rotating plate assembly returns to horizontal, allowing the cattle and sheep to leave the car.
