Description

Technical Field

[0001] The utility model belongs to the technical field of material storage equipment, and specifically relates to a single-drive right-angle plug sliding door. Background Art

[0002] The plug-in door structures currently involved are mostly traditional plug-in doors that use curved guide rails to achieve plug-in action and right-angle plug-in doors that use dual drives. According to the literal meaning, plug-in doors have two actions when opening and closing the door, one is the push-pull action when opening and closing the door, and the other is the push-in action when the two doors are closed together. The difference between traditional plug-in doors and right-angle plug-in doors lies in the push-in action. Both the push-pull action is completed by linear guides and linear guide rails. The push-in action of traditional plug-in doors is completed by curved guide rails. When the linear push-pull sections of the two doors are about to reach the closed area, the door guide rails will have an inward bending arc, and the door will achieve the push-in action through the arc. The right-angle plug-in door completes the push-pull and push-in actions through two power systems. When the two doors are closed in the linear push-pull section, the second power system intervenes to complete the push-in action.

[0003] The existing mechanism has the following disadvantages: since the right-angle sliding door requires two sets of drives to complete the full set of actions, the transmission system is relatively complex and prone to failure in harsh environments; since the traditional Sierra door uses an arc guide rail, there will be a certain gap between the two sides of the door and the door frame when the door is closed, which increases the difficulty of sealing; all Sierra door drives are set inside the compartment, and the mechanism cannot be used when there is high temperature, low temperature, flammable materials and volatile gases inside the compartment; servo motors or stepper motors are mostly used to realize the opening and closing drive of the door, but explosion-proof motors need to be used in explosion-proof environments, which makes the production cost of the door high. Utility Model Content

[0004] The purpose of the utility model is to provide a single-drive right-angle plug sliding door to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A single-drive right-angle plug sliding door comprises a door frame, a left door leaf, a right door leaf, a driving assembly, a power unit and a traction rope, wherein the driving assembly is fixed on the upper inner side of the door frame, the left door leaf and the right door leaf are arranged in cooperation with the door frame, the left door leaf and the right door leaf are respectively connected to the driving assembly, the power unit is arranged on the inner side or the outer side of the door frame, the middle part of the traction rope is connected to the driving assembly, and the two ends are connected to the power unit;

[0007] The size and shape of the door frame and the left and right door leaves are designed according to the specific requirements of the material warehouse. The door leaves can be special-shaped doors as long as they do not affect the plane sealing to meet the use requirements. The power unit is connected to the drive assembly through a traction rope and can be installed on the outside of the warehouse to avoid contact with the harsh environment inside the warehouse.

[0008] A driving assembly, the driving assembly comprising an elastic support seat, a guide shaft 1, a left door connecting piece, a right door connecting piece, and a sliding sleeve;

[0009] The elastic support seat includes a mounting support, a sliding seat, a movable pulley, a steering pulley, a guide shaft 2, and a compression spring. The sliding seat is fixed on the mounting support, the movable pulley is arranged on the sliding part of the sliding seat, the steering pulley is arranged on the mounting support, the guide shaft 2 is arranged between the movable pulley and the steering pulley, and the compression spring is sleeved on the guide shaft 2;

[0010] The elastic support seats are divided into two groups, which are respectively arranged on both sides of the upper part of the door frame. The two ends of the guide shaft 1 are respectively fixed on the sliding parts of the sliding seats on the elastic support seats. The sliding sleeves are divided into two groups, which are respectively slidably arranged on the guide shaft 1. The left door connecting piece is connected to one of the sliding sleeves, and the right door connecting piece is connected to the other sliding sleeve. The left door connecting piece is fixedly connected to the left door leaf, and the right door connecting piece is fixedly connected to the right door leaf.

[0011] One end of the drive assembly is connected to the door leaf, and the door leaf is pushed and pulled along the sliding sleeve to open and close. At the same time, there is a push-in (plug) mechanism inside, and a compression spring is used to push the door in (plug). The door connector is connected to the door leaf to control the movement of the door leaf. The mounting bracket is connected to the door frame to complete the relative fixation of the entire door leaf. The door connector is connected to the sliding sleeve and pushes and pulls through the guide shaft 1. When the door leaf is closed, since it can no longer move in the opening and closing direction of the door leaf, the compression spring will be squeezed at this time, and the door leaf will be pushed in (plugged) along the guide shaft 2.

[0012] The movement of the door leaf is powered by a traction rope. Each door connector has a traction rope fixing seat where the traction rope is fixed. The traction rope will pass through the moving pulley and the steering pulley and lead out of the warehouse. Figure 2 As shown in the figure, taking the left door as an example, the A1 traction rope is the driving force for closing the door, and the A2 traction rope is the driving force for opening the door.

[0013] When the left door leaf needs to be closed, the A1 traction rope will be pulled outward along the moving pulley and the steering wheel. At this time, the door will be closed along the guide shaft 1. Similarly, the right door leaf will also be closed together. When the left and right door leaves are closed in a straight line, they can no longer be pulled in a straight line. At this time, the moving pulley and the steering pulley will be compressed. There will be a compression spring between the two pulleys for support. Under normal conditions, there will be a certain distance between the moving pulley and the steering pulley due to the existence of the spring. After the spring is compressed, the door leaf will move through the guide shaft 2, and the door will be pushed in (plugged).

[0014] When the left door leaf needs to be opened, the A2 traction rope will be pulled outward along the moving pulley and the steering wheel, and the door leaf will be opened along the guide shaft 1. Since A1 and A2 are composed of the same traction rope, the compression force of the moving pulley and the spring disappears at this time, so the door leaf will first be pushed out (plugged). Then the A2 traction rope will be pulled outward along the moving pulley and the steering wheel, and the door leaf will be opened along the guide shaft 1 until it is fully opened. Similarly, the right door leaf will also be opened together.

[0015] In a preferred solution, it also includes a follower connecting rod assembly and a supporting guide rail;

[0016] The follower link assembly includes a seat bearing A, a rotating shaft, an auxiliary bending beam, and a pulley block. The follower link assembly consists of two groups, which are symmetrically arranged on both sides of the door frame.

[0017] The seat bearing A is a connecting piece between the follower link assembly and the door frame, which not only ensures the auxiliary support of the door but also ensures that the follower link assembly can rotate smoothly.

[0018] The seat bearing A is fixed on the door frame, the rotating shaft passes through the seat bearing A, one end of the auxiliary curved beam is fixedly connected to the rotating shaft, and the other end of the auxiliary curved beam is hinged to the pulley block; the follower connecting rod assembly is respectively connected to the driving assembly and the supporting guide rail of the door, which plays an auxiliary support role and can assist the pushing (exiting) action after being connected to the driving assembly through the rotating connecting rod.

[0019] The auxiliary curved beam and roller group are equipped together to form a support assembly. The auxiliary curved beam is fixedly connected to the rotation. At this time, the weight of the door leaf will be transmitted to the rotating shaft through the roller group and the auxiliary curved beam to strengthen the structural strength. When the rotating shaft rotates, the auxiliary curved beam can be used to achieve auxiliary push-in (out) action. Since the roller group is slidably connected to the door leaf support rail, the auxiliary curved beam can play a certain compensation role when there is a certain speed difference with the door leaf when rotating.

[0020] The support rails are symmetrically arranged on the left door leaf and the right door leaf, and the support rails are connected with the pulley block. Since there is only one connection point between the door leaf and the drive assembly, the support rails are required to achieve auxiliary support to improve the stability and operability of the door leaf.

[0021] In a preferred solution, the support rails are divided into two groups, namely upper support rails and lower support rails. The upper support rails are respectively arranged on the upper part of the left door leaf and the right door leaf, and the lower support rails are arranged on the lower part of the left door leaf and the right door leaf.

[0022] Furthermore, the supporting rail is a C-shaped steel rail.

[0023] Since there is only one connection point between the door leaf and the drive assembly, a support rail is required for auxiliary support. The support rail cooperates with the follower link assembly to achieve the support function. The follower link assembly is equipped with a roller group, which can roll inside the support rail. The weight of the door leaf is distributed to the frame through the support rail through the roller group to reduce the deformation of the drive assembly caused by the weight of the door leaf or the deformation of the door leaf caused by the small number of connection points of the door leaf. At the same time, in addition to the upper and lower surfaces of the support rail supporting the weight of the door leaf, the left and right surfaces also provide auxiliary support during the process of pushing the door leaf in (out) through contact with the roller group.

[0024] In a preferred solution, it also includes a rotating connecting rod and a follower connecting rod. The rotating connecting rod is arranged at the upper end of the rotating shaft, the follower connecting rod is connected to the sliding part of the sliding seat, and the rotating connecting rod is hinged to the follower connecting rod.

[0025] The rotating connecting rod is used to assist the door leaf in pushing in (out), and is hinged with the follower connecting rod of the driving assembly. When the follower connecting rod moves, it can drive the rotating connecting rod to rotate around the rotating shaft. This movement can meet the auxiliary pushing in (out) action.

[0026] In a preferred solution, the traction ropes are steel wire ropes, and the number is two.

[0027] In a preferred solution, the power unit includes a mounting seat, a cylinder, a rack, a gear, a reel, a seat bearing B, and a rotating shaft. The seat bearing B is fixed on the mounting seat, a rotating shaft is arranged on the seat bearing B, a gear is fixed on the rotating shaft, two reels are arranged at both ends of the rotating shaft, the cylinder body is fixed on the mounting seat, the cylinder action end is hinged to one end of the rack, and the tooth surface of the rack cooperates with the gear.

[0028] In a preferred solution, it also includes two sets of traction guide wheels, which are arranged on the mounting seat and matched with the two reels. The traction guide wheels guide the traction rope. After the traction rope is wound around the reel, the outlet line should be at the upper and lower ends. Therefore, the traction guide wheels are used to gather the traction rope together, which is convenient for arranging the direction of the traction rope.

[0029] In a preferred solution, a rack guide wheel is also included, which is fixed on the mounting seat and matched with the rack position. When the rack moves linearly, the rack guide wheel can constrain the normal freedom of the gear and reduce the friction force of the rack during linear motion.

[0030] The power unit is connected to the drive assembly by a traction rope and can be installed outside the cabin to avoid contact with the harsh environment inside the cabin. Figure 5 Middle traction ropes A1, A2, B1, B2 are all Figure 2 Each drive unit corresponds to a traction rope. All actions of the sliding plug door are achieved through the movement of the traction rope.

[0031] The power unit cylinder is responsible for outputting power. The cylinder action end is hinged to the rack through the cylinder hinge shaft. It drives the rack when extending and retracting. The linear motion of the rack drives the gear to rotate. The gear, shaft and reel are relatively fixed. When the gear rotates, it drives the reel to rotate. A traction rope is wound above the reel. When the reel rotates, it will reel in or release the traction rope, and the traction rope will drive the door leaf to open and close.

[0032] Compared with the prior art, the beneficial effects of the utility model are:

[0033] 1. By adopting the right-angle plug-in form, the gap between the door and the door frame is reduced, and the difficulty of sealing is reduced.

[0034] 2. A compression spring reset and connecting rod mechanism are used to achieve the purpose of a single drive unit driving the plug-in action, which is used to reduce the failure rate of the plug-in door.

[0035] 3. The power unit of the drive unit is extended to the outside of the chamber through the connection of steel wire ropes to be compatible with use under high temperature, low temperature, flammable materials and volatile gas conditions.

[0036] 4. The use of cylinders to control the door opening and closing reduces the use cost in explosion-proof environments. At the same time, due to the use of compression spring buffering, the door can be opened and closed without precise control.

[0037] By solving the above four problems, the door's manufacturing cost, sealing difficulty, and failure rate can be reduced while allowing it to be used in harsh environments. BRIEF DESCRIPTION OF THE DRAWINGS
