Description

Technical Field

[0001] The invention relates to the technical field of automatic assembly of elevator guide rails, in particular to an automatic conveying device for elevator guide rails. Background Art

[0002] As the height of buildings increases, people need to use elevators to quickly climb to higher building heights. Elevator guide rails are an important component of elevators. During the elevator assembly process, the elevator guide rails need to be transported to the corresponding positions to facilitate assembly by staff. However, since the elevator guide rails themselves are very heavy, manual transportation is not only time-consuming and labor-intensive, but also prone to safety problems. Therefore, most elevator production workshops use mechanized conveying equipment to transport elevator guide rails.

[0003] The existing elevator guide rails are usually transported by connecting multiple sets of conveying equipment end to end, and supporting the elevator guide rails through the conveying mechanism arranged inside. For example, Chinese patent publication number CN217894192U discloses an automatic conveying device for elevator guide rails, which can not only adjust the height of the conveying equipment, but also automatically transport and facilitate repair and maintenance.

[0004] However, when the above-mentioned conveying device is transporting, since the elevator guide rails themselves have a certain mass, and when there is a conveying height difference between two adjacent conveying devices, the height difference from top to bottom may cause the elevator guide rails to impact and damage the conveying device below. Not only may the elevator guide rails themselves become stuck, but the elevator guide rails may also deviate, thereby affecting the normal transportation effect of the device. In view of this, we propose an automatic conveying device for elevator guide rails. Summary of the invention

[0016] Compared with the prior art, the present invention provides an automatic conveying device for elevator guide rails, which has the following beneficial effects:

[0017] 1. The automatic conveying device for elevator guide rails is provided with a protective component, and cooperates with the setting of the elastic telescopic rod and the positioning arc plate in the positioning sleeve to protect the impact that may be generated when the elevator guide rail is unloaded, and cooperates with the continuous movement of the transmission belt to make the round rod in the transmission groove rotate continuously, thereby driving the rotating rod, the connecting rod and the contact roller to rotate. When the contact roller rotates to the upper side, the contact roller contacts the bottom surface of the elevator guide rail, and through the flipping of the contact roller, the elevator guide rail is pushed to ensure that the elevator guide rail can be stably transmitted forward during transmission without getting stuck, so as to ensure the stability of the elevator guide rail during transmission.

[0018] 2. The automatic conveying device for the elevator guide rail is provided with a deceleration assembly. When the rotating rod rotates, due to the staggered arrangement of the trapezoidal block and the protrusion, the reset spring and the rounded corner design at the edges of the trapezoidal block and the protrusion, the movable sleeve will be laterally displaced along the outer surface of the short rod, thereby reducing the smoothness of the rotating rod during rotation through this movement process, thereby making the rotating rod rotate at a lower speed, so as to ensure the stability of the contact roller during auxiliary pushing and resetting, and thus ensure the stability of the elevator guide rail during transmission.

[0019] 3. The automatic conveying device for elevator guide rails is provided with a correction component. The elevator guide rails will contact the round rods during the conveying process, and the surface of the elevator guide rails will directly contact and squeeze the outer surface of the correction plate. During the squeezing process, due to the inclined setting of the correction plate itself in its initial state and the elastic force of the coil spring, the elevator guide rails will not deviate during the transmission process, ensuring that they are transported in a correct posture, thereby avoiding dangers in the subsequent unloading and transmission process.

[0020] 4. The automatic conveying device for elevator guide rails is provided with a gripping assembly. When the transmission roller contacts the bottom surface of the elevator guide rail, it cooperates with the arrangement of multiple sets of sleeves. Under the action of the transmission force of the spring, it cooperates with several sets of convex balls arranged in a spiral array to ensure that the contact roller drives the elevator guide rail, thereby improving the transportation effect of the device.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figure 1-Figure 9 As shown, the present invention provides a technical solution: an automatic conveying device for elevator guide rails, comprising a frame 1, a stepper motor 2 is fixedly installed on the side wall of the frame 1, a transmission roller 3 is fixedly installed on the output end of the stepper motor 2, a transmission belt 4 is connected to the arc-shaped outer wall of the transmission roller 3, and a protection component 5 for protecting and pushing the elevator guide rail transmitted from top to bottom is arranged at the center of the frame 1, and the protection component 5 includes a transmission groove 51, a U-shaped holder 52, a positioning sleeve 53, an elastic telescopic rod 54, a positioning arc plate 55, a round rod 56, a contact belt 57, a rotating rod 58, a connecting rod 59, a contact roller 510 and a volute spring 511.

[0034] Furthermore, the center of the frame 1 is hollow to facilitate the arrangement of the transmission rollers 3 and the transmission belt 4, and the reserved space in the center of the frame 1 can facilitate the transportation of the elevator guide rails. At the same time, there are two groups of transmission rollers 3, and the two groups of transmission rollers 3 are mirror-imaged on the left and right sides of the vertical center axis of the frame 1, so that when the stepping motor 2 is started, the transmission of the transmission belt 4 is coordinated to make the two groups of transmission rollers 3 rotate to realize the transmission of the elevator guide rails. In addition, the transmission groove 51 is set in a circular shape, so that when the transmission belt 4 is in a circular motion, the round rod 56 can always be inside the transmission groove 51. Specifically, the outer diameter of the positioning sleeve 53 is adapted to the inner diameter of the U-shaped holder 52, so that the positioning sleeve 53 can be stably embedded and installed in the U-shaped holder 52 to complete the installation of the positioning sleeve 53. Further, the number of the U-shaped holder 52 is set to be several The plurality of U-shaped clamping seats 52 are evenly distributed on the outer surface of the transmission belt 4 away from the transmission roller 3, so that the transmission belt 4 can drive the U-shaped clamping seat 52 and the positioning sleeve 53 to move during continuous movement. At the same time, the interior of the positioning sleeve 53 is hollow, and the number of elastic telescopic rods 54 is three groups, and the three groups of elastic telescopic rods 54 are evenly distributed on the arc-shaped inner wall of the positioning sleeve 53 in a circular array, and the positioning arc plates 55 corresponding to the three groups of elastic telescopic rods 54 are arranged in a circular ring shape in the same plane, so as to stably clamp the round rod 56 on its periphery and provide timely buffer protection when it is subjected to external force. Specifically, the arc-shaped outer wall of the positioning arc plate 55 close to the center side of the positioning sleeve 53 fits with the arc-shaped outer surface of the round rod 56, so that the positioning arc plate 55 can better clamp and position the round rod 56.

[0035] In addition, there are several groups of contact belts 57, and several groups of contact belts 57 are equidistantly distributed on the arc-shaped outer wall of the positioning arc plate 55 on one side near the center of the positioning sleeve 53. Specifically, the contact belt 57 is made of rubber belt, and a trapezoidal groove is provided on the outer surface of the contact belt 57, so that the contact belt 57 will be compressed and deformed when the positioning arc plate 55 contacts the round rod 56, and the trapezoidal groove is provided to prevent lateral displacement between the round rod 56 and the positioning arc plate 55, thereby ensuring the positioning and clamping stability of the positioning arc plate 55 on the round rod 56. Furthermore, an inverted "J"-shaped structure is formed between the round rod 56, the connecting rod 59 and the contact roller 510, and the rotating rod 58 is rotatably connected to the inner wall of the round rod 56, and the end of the round rod 56 is in contact with the bottom inner wall of the transmission groove 51, so that the transmission belt 4 drives the U-shaped seat 52 and the positioning sleeve 53 along the inner surface of the transmission groove 51 When displacing, the round rod 56 will continue to rotate, thereby driving the rotating rod 58, the connecting rod 59 and the contact roller 510 to rotate, so that in the process of the transmission belt 4 transmitting the elevator guide rail, the contact roller 510 will rotate with the rotating rod 58 as the rotation center, and then push the elevator guide rail to ensure that the elevator guide rail can be stably transmitted forward during transmission without getting stuck, so as to ensure the stability of the elevator guide rail during transmission. Furthermore, the two ends of the spiral spring 511 are respectively fixedly connected to the arc-shaped outer wall of the rotating rod 58 and the inner wall of the round rod 56, so that when the rotating rod 58 rotates, due to the elastic force of the spiral spring 511, the rotating rod 58 always has a movement tendency of rotating in the opposite direction to achieve reset, and then after the rotating rod 58 cooperates with the connecting rod 59 to drive the contact roller 510 to push the elevator guide rail, the rotating rod 58 will be reset in time to facilitate the subsequent continued pushing operation.

[0036] Specifically, the interior of the round rod 56 is provided with a deceleration assembly 6 which can prevent the contact roller 510 from shaking repeatedly after being pushed and affecting the stable transmission of the elevator guide rail. The deceleration assembly 6 includes a transmission cavity 61. The inner wall of the end of the round rod 56 away from the frame 1 is provided with a transmission cavity 61. A trapezoidal block 62 is fixedly installed on the arc-shaped outer wall of the rotating rod 58. A short rod 63 is fixedly installed on the inner wall of the end of the transmission cavity 61. A movable sleeve 64 is slidably installed on the outer wall of the short rod 63. A reset spring 65 is fixedly connected between the inner wall of the end of the movable sleeve 64 and the end of the short rod 63. A protrusion 66 is fixedly installed on the upper surface of the movable sleeve 64.

[0037] Specifically, the rotating rod 58 is arranged inside the transmission chamber 61, and the end of the spiral spring 511 is fixedly mounted on the inner wall of the transmission chamber 61, and the end of the rotating rod 58 is rotatably connected to the inner wall of the transmission chamber 61. At the same time, the short rod 63 is arranged in a square shape, and a square groove adapted to the short rod 63 is opened inside the movable sleeve 64, so that the movable sleeve 64 can only move in the horizontal direction along the outer wall of the short rod 63. Furthermore, the edges of the protrusion 66 and the trapezoidal block 62 are both rounded, and the protrusion 66 and the trapezoidal block 62 are staggered, so that the rotating rod 58 can be rotated. When rotating inside the transmission cavity 61, due to the relative displacement between the rotating rod 58 and the movable sleeve 64, the trapezoidal block 62 will first contact the protrusion 66, and through the rounded corner design at the edges of the trapezoidal block 62 and the protrusion 66, the movable sleeve 64 will be laterally displaced along the outer surface of the short rod 63, so that the smoothness of the rotating rod 58 during rotation is reduced through this movement process, and the rotating rod 58 is rotated at a lower speed to ensure the stability of the contact roller 510 during auxiliary pushing and resetting, thereby ensuring the stability of the elevator guide rail during transmission.

[0038] In one embodiment of the present invention, a correction component 7 is provided inside the round rod 56 for centering and correcting a slightly offset elevator guide rail. The correction component 7 includes a storage cavity 71. The storage cavity 71 is provided on the arc-shaped outer wall of the round rod 56. A rotating rod 72 is rotatably installed on the inner wall of the storage cavity 71. The rotating rod 72 passes through a correction plate 73, and the correction plate 73 is fixedly connected to the rotating rod 72. A coil spring 74 is sleeved on the arc-shaped outer wall of the rotating rod 72, and an arc strip 75 is provided on the top outer wall of the correction plate 73.

[0039] Specifically, there are eight correction components 7, and the eight correction components 7 are evenly distributed on the arc-shaped outer wall of the round rod 56 in a circular array, so that the eight correction components 7 can push and position the elevator guide rail above the round rod 56 when the round rod 56 is rotated to any angle. At the same time, the width of the correction plate 73 is adapted to the width of the storage cavity 71, and the top outer wall of the correction plate 73 is set to an arc shape that matches the outer surface of the round rod 56, so that the correction plate 73 can be completely received in the storage cavity 71. Furthermore, the inner wall of the storage cavity 71 is provided with a circular hole with a diameter larger than the outer diameter of the coil spring 74, and the two ends of the coil spring 74 are respectively fixedly connected to the arc-shaped outer wall of the rotating rod 72 and the bottom inner wall of the circular hole, so that when the rotating rod 72 rotates, due to the elastic force of the coil spring 74, The rotating rod 72 always has the movement tendency to drive the correction plate 73 to rotate in the opposite direction to achieve reset. At the same time, the arc bar 75 is arranged in a wave shape, and the number of arc bars 75 is arranged in multiple groups, and the multiple groups of arc bars 75 are arranged in a linear array on the top outer wall of the correction plate 73. In the initial state, due to the elastic force of the coil spring 74, the rotating rod 72 drives the correction plate 73 to swing toward the center of the frame 1, so that the outer surface of the elevator guide rail in contact with the round rod 56 will directly contact the outer surface of the correction plate 73 and achieve extrusion. In the extrusion process, due to the inclined setting of the correction plate 73 itself in the initial state and the elastic force of the coil spring 74, the elevator guide rail will not deviate during the transmission process, ensuring that it is transported in the correct posture, thereby avoiding danger in the subsequent unloading and transmission process.

[0040] In an embodiment of the present invention, a gripping assembly 8 that can improve the gripping force on the elevator guide rail is provided on the arc-shaped outer wall of the contact roller 510, and the gripping assembly 8 includes a connecting rod 81, and the connecting rod 81 passes through the axis of the contact roller 510, and the connecting rod 81 is fixedly connected to the contact roller 510, and a mounting groove 82 is opened on the arc-shaped outer wall of the contact roller 510, and a sleeve 83 is sleeved inside the mounting groove 82, and a convex ball 84 is provided on the arc-shaped outer wall of the sleeve 83, and a spring 85 is fixedly connected between the connecting rod 81 and the arc-shaped inner wall of the sleeve 83.

[0041] It is worth noting that there are three groups of mounting grooves 82, and the three groups of mounting grooves 82 are equidistantly distributed on the arc-shaped outer wall of the contact roller 510. Specifically, annular limit grooves are provided on the left and right inner walls of the mounting grooves 82, and positioning rings matched with the above-mentioned annular limit grooves are provided on the left and right outer walls of the sleeve 83 to ensure that the rotation of the sleeve 83 on the contact roller 510 is more stable, thereby effectively avoiding the compression deformation of the sleeve 83 and affecting the normal transportation of the elevator guide rail. At the same time, there are several groups of convex balls 84, and several groups of convex balls 84 are evenly distributed on the arc-shaped outer wall of the sleeve 83 in a spiral array, so that no matter what angle the sleeve 83 rotates to, there are enough convex balls 84 on the arc-shaped outer surface of the sleeve 83 to provide transmission gripping force, thereby ensuring the stable transmission of the elevator guide rail and avoiding the situation where it cannot be stably supplied.

[0042] As an application of this embodiment:

[0043] The elevator guide rail is input from the right side of the frame 1 to the left side. At this time, the stepper motor 2 is started to cooperate with the transmission roller 3 to make the transmission belt 4 start to move. When the elevator guide rail input from the right side of the frame 1 just contacts the transmission belt 4, the protection component 5 is provided to cooperate with the elastic telescopic rod 54 and the positioning arc plate 55 in the positioning sleeve 53 to protect the impact that may be generated when the elevator guide rail is unloaded, and the end of the round rod 56 is fitted with the bottom inner wall of the transmission groove 51. When the transmission belt 4 drives the U-shaped card seat 52 and the positioning sleeve 53 to move along the inner surface of the transmission groove 51, the round rod 56 will continue to rotate, thereby driving the rotating rod 58, the connecting rod 59 and the contact roller 510 to rotate. When the contact roller 510 rotates to the top, the contact roller 510 will contact the bottom surface of the elevator guide rail, and through the flipping of the contact roller 510, the elevator guide rail is pushed to ensure that the elevator guide rail can be stably transmitted forward during transmission without getting stuck, so as to ensure the stability of the elevator guide rail during transmission.

[0044] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
