Description

Technical Field

[0001] This utility model relates to the field of automobile production technology, specifically to a ground-pushing chain conveyor. Background Technology

[0002] In an automotive painting workshop, car bodies (usually fixed on a ground-based trolley) need to be transported between various process stages (such as pretreatment, electrophoresis, spraying, baking, etc.).

[0003] Currently common conveying equipment includes skid conveyor systems and accumulating conveyor chains. Traditional skid conveyor systems typically use a large number of roller beds as basic conveying units. However, roller beds have complex structures, large footprints, high manufacturing and maintenance costs, and generate significant noise during operation. While accumulating conveyor chains are widely used, their safety needs improvement in situations requiring precise positioning and prevention of trolley slippage due to inertia. Especially during production line start-ups, shutdowns, accelerations, and decelerations, trolleys are prone to detaching from or colliding with the pusher, affecting the smoothness and safety of the conveyor and generating considerable noise. Therefore, there is an urgent need in this field for a conveying device that is simple in structure, operates smoothly, has low noise, and can effectively prevent trolleys from detaching during acceleration and deceleration. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a ground-pushing chain conveyor that can reduce noise, lower maintenance costs, and effectively prevent the conveyor trolley from detaching from the conveyor during acceleration and deceleration, thereby improving the safety and reliability of the conveying process and effectively solving the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ground-pushing chain conveyor, comprising:

[0006] The guard plate assembly includes two rows of parallel guard plates, each row of guard plates being connected by several plate bolts;

[0007] A drive rotation mechanism is provided at one end of the guard plate assembly, including a motor housing, a drive motor, a rotating shaft, a drive sprocket, a driven sprocket, and a driven sprocket shaft. The motor housing is fixed to the outer side of the guard plate assembly, the drive motor is installed inside the motor housing, the rotating shaft is installed inside the guard plate assembly, and the output end of the drive motor is connected to the rotating shaft. Two drive sprockets are provided on the outer side of the rotating shaft, and the driven sprocket shaft is installed at the other end of the guard plate assembly. Two driven sprockets are installed on the outer side of the driven sprocket shaft, and the two drive sprockets and the two driven sprockets correspond one-to-one.

[0008] A ring chain is fitted between the driving sprocket and the driven sprocket on the same side, respectively;

[0009] The pusher assembly consists of several groups mounted on the chain plate of the same annular chain. Each pusher assembly includes two symmetrically arranged pushers to limit the movement of the trolley carrying the vehicle body. The pushers are rotatably connected to the chain plate of the annular chain via pins. The pushers have a V-shaped structure, and the weight of one end of the pusher is much greater than the weight of the other end.

[0010] As a preferred embodiment of this utility model, the upper and lower outer sides of the annular chain are provided with chain pressing components. The chain pressing components include a mounting plate and a pressing head. The mounting plate is installed inside the guard plate assembly. The pressing head is provided on the inner side of the mounting plate and the pressing head corresponds to the position of the annular chain.

[0011] As a preferred embodiment of this invention, the contact surface between the pressure head and the annular chain is coated with a non-metallic self-lubricating layer.

[0012] As a preferred technical solution of this utility model, a tension adjustment mechanism is symmetrically arranged on the outer side of the guard plate assembly near the driven sprocket end, for adjusting the tension of the ring chain.

[0013] As a preferred embodiment of this utility model, the tension adjustment mechanism includes an adjustment block, a screw, a fixing block, and a locking nut;

[0014] The outer surfaces of both side plates of the guard plate assembly corresponding to the driven sprocket position are provided with strip-shaped holes. The two ends of the driven sprocket shaft pass through the strip-shaped holes and are rotatably connected to the adjusting block. A screw is fixedly connected to one side of the adjusting block. The fixing block is fixed to the guard plate assembly. The screw passes through the fixing block. Two locking nuts are threaded to the outer surface of the screw. The two locking nuts are located on both sides of the fixing block.

[0015] As a preferred embodiment of this utility model, the lower end of the guard plate assembly is provided with a plurality of height-adjustable support feet.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: The local push chain conveyor is reasonably designed and ingeniously conceived. By setting up double-row chains, the stability of the sled conveyor is ensured. By setting up several push head assemblies on the ring chain, and using two push heads in the push head assembly to limit the trolley, the problem of the conveying trolley disengaging from the push head due to inertia when decelerating and stopping is solved, which greatly improves the safety and reliability of the conveying process. By setting up a chain pressing assembly, the ring chain is prevented from jumping, maintaining the smooth operation of the conveying process. Furthermore, by coating the chain pressing assembly with a self-lubricating material, wear between the metal chain and the metal is reduced, which also reduces noise, extends the service life of the equipment, and reduces maintenance costs.

[0025] 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 (for ease of description and understanding, hereinafter referred to as...). Figure 2 (The above is described above). Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Please see Figure 1-7 This utility model provides a technical solution: a ground-pushing chain conveyor, including a guard plate assembly 1, a drive rotation mechanism 2, an annular chain 3, and a pusher assembly 4;

[0027] The guard plate assembly 1 includes two rows of parallel guard plates. Each row of guard plates is connected by several plate bolts to form a frame that protects the ring chain 3. In order to improve the height adaptability of the equipment and the trolley to be transported, multiple height-adjustable support legs 8 are evenly distributed at the lower end of the guard plate assembly 1. The support legs 8 are fixed to the lower end of the guard plate assembly 1 by screws and nuts.

[0028] The drive rotation mechanism 2 includes a motor housing 21, a drive motor 22, a rotating shaft 23, a drive sprocket 24, a driven sprocket 25, and a driven sprocket shaft 26. The motor housing 21 is fixed to the outer side of one end of the guard plate assembly 1. The drive motor 22 is installed inside the motor housing 21. The rotating shaft 23 is installed inside the guard plate assembly 1. The output end of the drive motor 22 is connected to the rotating shaft 23. Two drive sprockets 24 are provided on the outer side of the rotating shaft 23. The driven sprocket shaft 26 is installed at the other end of the guard plate assembly 1. Two driven sprockets 25 are installed on the outer side of the driven sprocket shaft 26. The two drive sprockets 24 and the two driven sprockets 25 correspond one-to-one. The annular chain 3 is respectively sleeved between the drive sprockets 24 and the driven sprockets 25 on the same side. The surface of the annular chain 3 is covered with chain plates, thus forming a double-row chain. Under the drive of the drive motor 22, the annular chain 3 performs a closed-loop cyclic motion, which can drive the trolley to move. By setting the double-row annular chain 3, the stability of the conveying process can be guaranteed.

[0029] The pusher assembly 4 is installed in several groups at intervals on the chain plate of the same ring chain 3. Each group of pusher assembly 4 includes two symmetrically arranged pushers. The installation spacing of the pusher assembly 4 can be changed according to the size of the trolley. The pushers are rotatably connected to the chain plate of the ring chain 3 through pins. The pushers have a V-shaped structure with the central axis of the pin as the dividing line. The weight of one end of the pusher is much greater than that of the other end. Under normal conditions, the heavier end of the pusher is parallel to the ring chain 3 under the action of gravity. When the trolley enters between two pushers, the pusher on the rear side lifts the heavier end under the pressure of the trolley body to limit and support it. When the ring chain 3 decelerates or stops, the trolley slides forward due to inertia. At this time, the pusher on the front side lifts the heavier end under the action of the trolley's gravity, thereby locking it at the bottom of the trolley and preventing it from falling off the conveying equipment.

[0030] In this embodiment, in order to limit the jumping of the ring chain 3 during the conveying process and ensure that the ring chain 3 is always correctly engaged with the drive sprocket 24 and maintains stable operation, a chain pressing assembly 5 is provided on the upper and lower outer sides of the ring chain 3. The chain pressing assembly 5 includes a mounting plate 51 and a pressing head 52. The mounting plate 51 is installed in the guard plate assembly 1, and the pressing head 52 is provided on the inner side of the mounting plate 51. The pressing head 52 corresponds to the position of the ring chain 3, thereby limiting the jumping of the ring chain 3.

[0031] Furthermore, the contact surface between the pressure head 52 and the ring chain 3 is coated with a non-metallic self-lubricating layer, which not only reduces the frictional resistance and wear of the ring chain 3, but also significantly reduces the operating noise.

[0032] In order to adjust the length of the entire conveying equipment according to the length of the production line, the length of the ring chain 3 can be changed according to the size of the site and the conveying length. After the length of the ring chain 3 is changed, a tension adjustment mechanism 6 is symmetrically arranged on the outer side of the guard plate assembly 1 near the driven sprocket 25 end to adjust the tension of the ring chain 3. The tension adjustment mechanism 6 includes an adjustment block 61, a screw 62, a fixing block 63 and a locking nut 64.

[0033] The outer surfaces of both side plates of the guard plate assembly 1 corresponding to the position of the driven sprocket 25 are provided with strip holes 7. The two ends of the driven sprocket shaft 26 pass through the strip holes 7 and are rotatably connected to the adjusting block 61. A screw 62 is fixedly connected to one side of the adjusting block 61. A fixing block 63 is fixed on the guard plate assembly 1. The screw 62 passes through the fixing block 63. Two locking nuts 64 are threadedly connected to the outer surface of the screw 62. The two locking nuts 64 are located on both sides of the fixing block 63. By loosening the locking nuts 64, the adjusting block 61 moves horizontally, thereby changing the position of the driven sprocket 25, so that the annular chain 3 always maintains a meshing state with the driving sprocket 24 and the driven sprocket 25.

[0034] In use: When the ground trolley carrying the vehicle body moves onto the ring chain 3, its rear end presses against the pusher head on the double-row ring chain 3, causing the heavier end of the pusher head to lift up and get into the corresponding slot at the bottom of the ground trolley. Under the action of the drive motor 22, the ring chain 3 is driven to rotate, thereby driving the ground trolley to move. When the drive motor 22 decelerates or stops, the ground trolley moves forward under the action of inertia. At this time, the pusher head at the front end is lifted up by the pressure of the ground trolley and gets into the bottom of the ground trolley, thus forming a backstop structure to prevent the ground trolley from moving forward until the ground trolley is moved to the handover position.

[0035] The parts of the utility model not described in detail are prior art. Although embodiments of the utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the utility model.
