DETAILED DESCRIPTION

[0033] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0034] As described in the background, current elevators utilize pneumatic cylinders to drive a support mechanism up and down, thereby changing the position of items mounted on the support mechanism. While pneumatic cylinders offer powerful propulsion, they can quickly raise and lower items. However, this rapid movement also presents a series of challenges. The instability of items during rapid lifting can easily lead to them slipping and, in extreme cases, even causing vibrations in the entire elevator, posing a threat to transport safety.

[0035] Based on this, the present application provides an elevator for construction, which aims to solve the technical problem of unstable and unsafe transportation caused by the excessively fast ascent and descent speed of the elevator in the prior art.

[0036] refer to Figure 1 and Figure 2A lift for construction, comprising: a slide rail 10; a sliding mechanism 20, configured to slide along the slide rail 10, the sliding mechanism 20 comprising a fixing member 200 and a sliding member 210, the fixing member 200 being provided with a through hole, the sliding member 210 being passed through the through hole; a connecting structure 30, provided on a side of the fixing member 200 having the through hole, and arranged in a direction close to the through hole; a deceleration mechanism 40, provided on one side of the sliding mechanism 20, the deceleration mechanism 40 comprising an elastic connecting member 400, the elastic connecting member 400 being connected to the connecting structure 30, and being configured to tighten the elastic connecting member 400 in a direction opposite to the sliding direction of the sliding mechanism 20 when the sliding mechanism 20 slides.

[0037] In one specific embodiment, a slide rail 10 is mounted on the surface of a column, extending along its height. The column is a rectangular parallelepiped made of steel or aluminum alloy, allowing the slide rail 10 to fit snugly against the column and prevent it from falling. An item is placed on the surface of a support mechanism 90, which is connected to a fixed member 200 on a side without a through hole. Driven by a drive mechanism 110, the item slides on the slide rail 10 via a sliding mechanism 20.

[0038] In a specific embodiment, there are multiple sliding members 210, and the fixing member 200 is provided with multiple through holes. All through holes are located on the same horizontal line, and a certain distance is maintained between adjacent through holes so that the sliding members 210 installed in the through holes will not touch each other during installation and sliding.

[0039] In a specific embodiment, the connecting structure 30 is extended along a side perpendicular to the fixing member 200 and provided with a through hole. The end of the connecting structure 30 away from the fixing member 200 is provided with a groove structure so that the elastic connecting member 400 can be mounted thereon to fix the position of the elastic connecting member 400 and avoid the elastic connecting member 400 from being disconnected from the connecting structure 30 due to position displacement during tightening.

[0040] In summary, in the scheme, the supporting mechanism 90 slides on the slide rail 10 through the sliding mechanism 20, and the driving mechanism 110 provides a driving force for the supporting mechanism 90. Through the cooperation of the deceleration mechanism 40 and the connecting structure 30, when the sliding mechanism 20 slides in a certain direction, the deceleration mechanism 40 tightens the elastic connecting member 400 in the opposite direction, exerting a certain resistance on the movement of the sliding mechanism 20, effectively slowing down the movement speed of the sliding mechanism 20, and reducing the instability and slipping risk of items caused by rapid lifting. At the same time, due to the action of the deceleration mechanism 40, the operation of the elevator is smoother, and the overall vibration is effectively controlled, thereby improving the safety and stability of the elevator during transportation.

[0041] Preferably, reference Figure 2The deceleration mechanism 40 further includes a first motor 410 and a second motor 420 . The first motor 410 is connected to one end of the elastic connector 400 , and the second motor 420 is connected to the other end of the elastic connector 400 through the connecting structure 30 .

[0042] In a specific embodiment, the deceleration mechanism 40 further includes a housing, and the first motor 410 and the second motor 420 are both disposed in the housing to avoid the influence of other components of the elevator on the motors and ensure the safety of the motors during operation.

[0043] In a specific embodiment, the output shaft of the first motor 410 is connected to the first reducer, the first reducer is connected to one end of the elastic connecting member 400, the output shaft of the second motor 420 is connected to the second reducer, and the second reducer and the elastic connecting member 400 are connected through the other end of the connecting structure 30. Through the setting of the reducer, it is avoided that in certain extreme cases, the motor speed is too fast, resulting in the force generated when tightening the elastic connecting member 400 being close to the driving force generated by the drive mechanism 110, causing the support mechanism 90 to move slowly, vibrate back and forth with a small amplitude in the original position, and cannot reach a normal operating state.

[0044] Preferably, reference Figure 2 The first motor 410 and the second motor 420 are arranged opposite to each other, and the rotation directions of the first motor 410 and the second motor 420 are opposite to each other, so as to tighten the elastic connecting member 400.

[0045] In a specific embodiment, Figure 2 As a reference, along the longitudinal direction of the column, a deceleration mechanism 40 is provided on both sides of the sliding mechanism 20. The first motor 410, the connecting structure 30, and the second motor 420 on both sides are connected by an elastic connector 400 to form a V-shape. Taking the motor and connecting structure 30 on the upper side as an example, when the driving mechanism 110 drives the support mechanism 90 to move downward, that is, when the sliding mechanism 20 moves downward along the slide rail 10, the output shaft of the first motor 410 rotates clockwise and the output shaft of the second motor 420 rotates counterclockwise, so that the elastic connector 400 is tightened, applying an upward pulling force to the connecting structure 30, thereby exerting a certain resistance to the downward movement of the sliding mechanism 20, effectively slowing down the movement speed of the sliding mechanism 20. Taking the motor and connecting structure 30 on the lower side as an example, when the driving mechanism 110 drives the supporting mechanism 90 to move upward, that is, when the sliding mechanism 20 moves upward along the slide rail 10, the output shaft of the first motor 410 rotates counterclockwise, and the output shaft of the second motor 420 rotates clockwise, so that the elastic connecting member 400 is tightened and a downward pulling force is applied to the connecting structure 30, so as to apply a certain resistance to the upward movement of the sliding mechanism 20, thereby effectively slowing down the movement speed of the sliding mechanism 20.

[0046] In summary, by tightening the elastic connector 400 through the symmetrically arranged and counter-rotating motors, the connecting structure 30 is pulled, thereby applying a certain resistance to the movement of the sliding mechanism 20, effectively slowing down the movement speed of the sliding mechanism 20, and reducing the risk of instability and slipping of items due to rapid lifting.

[0047] Preferably, reference Figure 3 and Figure 4 The sliding member 210 includes: a rotating body, including a rotating shaft 2100 and bearings 2110 provided at both ends of the rotating shaft 2100; a sliding body, sleeved on the rotating body, and configured to rotate with the rotation of the bearing 2110, the sliding body includes a first cylinder 2120 and a second cylinder 2130 provided at both ends of the first cylinder 2120, the second cylinder 2130 and the bearing 2110 are fit together, the first cylinder 2120 is passed through the through hole, and the second cylinder 2130 abuts against both sides of the slide rail 10, for sliding along the slide rail 10 and limiting the sliding position of the sliding body on the slide rail 10, wherein the bottom area of ​​the first cylinder 2120 is smaller than the bottom area of ​​the second cylinder 2130.

[0048] The length of the rotating body is slightly longer than that of the sliding body. Bearings 2110 are fixed at both ends of the rotating shaft 2100 and rotate relative to the rotating shaft 2100. Second cylindrical bodies 2130 at each end of the sliding body engage and clamp with the corresponding bearings 2110, rotating synchronously with the bearings 2110 in any direction. Furthermore, when the sliding body rotates, the second cylindrical bodies 2130 abut against both sides of the slide rail 10 to limit the sliding position of the sliding body on the slide rail 10, preventing the sliding body from deviating from the track and causing lifting failures, thereby ensuring the stability and reliability of the elevator during the lifting process.

[0049] In a specific embodiment, the first cylinder 2120 passes through the through hole and rotates synchronously with the second cylinder 2130 , or the first cylinder 2120 is fixed in the through hole and the second cylinder 2130 rotates.

[0050] In one embodiment, the second cylindrical body 2130 and the first cylindrical body 2120 are threadedly connected at both ends. During installation of the sliding member 210 and the fixing member 200, the first cylindrical body 2120 is first inserted into the through-hole, and then the second cylindrical body 2130 is screwed into both ends of the first cylindrical body 2120. Even if a sliding member 210 is damaged, only the second cylindrical body 2130 at one end needs to be removed, and then the first cylindrical body 2120 can be removed. This makes replacement quick and easy, and reduces maintenance costs.

[0051] In summary, the arrangement of the sliding member 210 enables the elevator to perform lifting actions smoothly, thereby improving the stability of the lifting process.

[0052] Preferably, reference Figure 1 The elevator also includes a first column 50, a second column 60, a base 70 and a top frame 80. The surfaces of the first column 50 and the second column 60 are provided with slide rails 10. The bottom ends of the first column 50 and the second column 60 are connected to the base 70, the top end of the first column 50 is connected to one end of the top frame 80, and the top end of the second column 60 is connected to the other end of the top frame 80, wherein a preset distance is maintained between the first column 50 and the second column 60.

[0053] In a specific embodiment, the columns include a first column 50 and a second column 60, and the first column 50 and the second column 60 are symmetrically arranged on the base 70. The top ends of the first column 50 and the second column 60 and the two ends of the top frame 80 are detachably connected. The top frame 80 can fix the top ends of the two columns to prevent the columns from tilting due to force when the sliding mechanism 20 drives the supporting mechanism 90 to move. The detachable connection allows the elevator to increase the length of the first column 50 and the second column 60 simultaneously when the height does not meet the preset conditions. The height meets the preset conditions, and then the top frame 80 is connected to fix the top ends of the two columns.

[0054] In a specific embodiment, reference Figure 1 The elevator is provided with four retarding mechanisms 40 in total, two retarding mechanisms 40 are symmetrically provided on both sides of the top frame 80, and two retarding mechanisms 40 are symmetrically provided on both sides of the base 70.

[0055] In a specific embodiment, a preset distance is maintained between the first column 50 and the second column 60, and the driving mechanism 110 can be placed between the two columns to save installation space of the elevator equipment.

[0056] In a specific embodiment, the lifting mechanism further includes a moving mechanism, which is disposed at the bottom of the base 70 and is used to drive the lift to move to a designated position.

[0057] Preferably, reference Figure 1 The elevator also includes a supporting mechanism 90, which includes a first group of plates 900, a second group of plates 910, a supporting shaft 920 and a supporting arm 930. The first group of plates 900 and the fixing member 200 are connected on one side without a through hole. The second group of plates 910 are symmetrically arranged at both ends of the first group of plates 900. The second group of plates 910 is provided with an axial hole, the supporting shaft 920 is passed through the axial hole, and the supporting arm 930 is fastened to the supporting shaft 920 and is configured to rotate with the supporting shaft 920.

[0058] In one embodiment, a support shaft 920 is located in front of the first set of plates 900. The ends of the support shaft 920 are inserted into two axial holes in the two opposing second sets of plates 910, allowing for clockwise and counterclockwise rotation. The support mechanism 90 includes two support arms 930, each equidistant from the corresponding axial hole.

[0059] Preferably, reference Figure 5 The supporting arm 930 includes a blocking portion 9300 and a supporting portion 9310 . One end of the blocking portion 9300 is connected to the supporting shaft 920 , and the other end away from the supporting shaft 920 is vertically connected to the supporting portion 9310 .

[0060] In a specific embodiment, Figure 5 As a reference, the supporting arm 930 is L-shaped, the shorter side is the blocking part 9300, and the longer side is the supporting part 9310. The supporting part 9310 is used to carry items, and the blocking part 9300 is used to allow items to lean against it, so that the center of gravity of the placed items moves forward and causes them to fall, thereby improving the safety of the lifting process.

[0061] Preferably, the supporting portion 9310 includes a multi-section telescopic structure, and adjacent telescopic structures are nested end to end. The telescopic structure is configured to extend a preset length or shrink to an initial length in a direction perpendicular to the blocking portion 9300, wherein the preset length is greater than the initial length.

[0062] In a partial embodiment, after the support arm 930 moves to a specified height, the telescopic structure extends a preset length to transport the items located thereon to a specified position, or the telescopic structure contracts to move the items located thereon from the specified position to a preset placement position on the support portion 9310. This allows the elevator to adapt to the requirements of different lengths of the support arm 930, thereby increasing the scope of use of the elevator.

[0063] Preferably, reference Figure 5 and Figure 6 The elevator also includes an adjustment mechanism 100, which is arranged between the first set of plates 900 and the support arm 930 and is configured to adjust the distance between the first set of plates 900 and the support arm 930 so that the support arm 930 is tilted upward along the height direction of the first column 50.

[0064] In a specific embodiment, the adjustment mechanism 100 includes a rotating telescopic screw, one end of which is connected to the first set of plates 900 and the other end is in contact with the blocking portion 9300. The rotating telescopic screw is configured to be adjustable in length. Figures 5 and 6As shown in the state change process, if an item is placed flat on the support portion 9310, and the center of gravity of the item is located away from the support point, it is offset to one side of the item, indicating that the weight of the item is mainly concentrated on the side away from the support point. In this case, the item may tip over from the support arm 930. When adjustment is required, simply turn the rotating telescopic screw toward the blocking portion 9300 to increase the length of the rotating telescopic screw, causing the support arm 930 to tilt upward and slightly tilt upward. As a result, when the item is placed on the support arm 930, it will not tip over, thus ensuring the safety of the item during lifting and transportation.

[0065] Preferably, reference Figure 1 The elevator also includes a driving mechanism 110, which is connected to the base 70 and is located between the first column 50 and the second column 60. The driving end of the driving mechanism 110 is connected to the bottom end of the first set of plates 900 to drive the supporting mechanism 90 to move.

[0066] In a specific embodiment, the driving mechanism 110 includes a cylinder, which includes a cylinder body and a piston rod that can move telescopically relative to the cylinder body. The cylinder body is arranged on the base 70 and is located between the first column 50 and the second column 60. The piston rod is connected to the middle position of the first group of plates 900.

[0067] In a specific embodiment, the cylinder body is vertically arranged along the height direction of the column, and the piston rod reciprocates along the height direction of the column to achieve the up and down movement of the supporting mechanism 90 through the sliding mechanism 20.

[0068] Preferably, the elevator also includes a locking mechanism (not shown in the figure), the driving mechanism 110 includes a cylinder, the locking mechanism is arranged between the first column 50 and the second column 60 in the direction close to the cylinder, and includes an elastic member and a locking member. The locking member and the elastic member are connected and are configured so that when the piston rod drives the first group of plates 900 to move to a preset position, the locking member is ejected by the elastic member to the front and rear sides of the sliding path of the sliding member 210 to block the sliding member 210 and stop it.

[0069] In a specific embodiment, the elevator also includes a position detection mechanism; during the operation of the elevator, the locking mechanism is in an unlocked state and the elastic member is in an energy storage state. When the elevator runs into position, that is, the position detection mechanism detects that the piston rod drives the first group of plates 900 to move to a preset position, the elastic member releases energy to drive the locking member out of the locking groove and get stuck in front and behind the sliding path of the sliding member 210, so that the sliding member 210 cannot continue to move, while keeping the current position of the piston rod fixed, so that the elevator is in a locked state and cannot move.
