Description

Technical Field

[0001] This utility model relates to the field of scaffolding technology, and in particular to a wall-mounted guide seat and an attached lifting scaffold. Background Technology

[0002] To improve the efficiency of building construction, climbing formwork is often used in the construction industry to replace traditional scaffolding. In climbing formwork equipment, the wall-mounted guide seat plays a guiding and fall-prevention role, and is a connecting bridge between the scaffolding and the wall.

[0003] According to prior art (publication number: CN217680402U), a wall-mounted guide seat is disclosed, including a roller gripper assembly, a main body and a C-shaped connector; the C-shaped connector is connected to the main body, the roller gripper assembly is embedded in the side of the C-shaped connector away from the main body, and the roller gripper assembly and the C-shaped connector are detachably connected.

[0004] In existing technologies, the guide rod is mainly guided by the guide wheel contacting the guide rod. In order to achieve fall prevention, a flip-up pendulum block is set to brake the guide rod. However, the guide wheel is still in a free-rotating state during braking. If the guide wheel can also brake the guide rod during braking, the fall prevention performance will be further improved, thereby improving safety and impact load resistance.

[0005] To address this, we propose a wall-mounted guide seat and an attached lifting scaffold. Utility Model Content

[0006] This utility model mainly solves the technical problem that the guide wheel cannot brake the guide rod when falling, and provides a wall-mounted guide seat and an attached lifting scaffold.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a wall-mounted guide seat and an attached lifting scaffold, comprising:

[0008] The main body has a mounting base fixedly installed on one side;

[0009] The gripper assembly is detachably mounted on one side of the mounting base and has two sets. The two sets of gripper assemblies are symmetrically distributed and the spacing can be adjusted. The gripper assembly includes a frame and guide wheels. The frame is locked to the mounting base by screws. Two guide wheels are symmetrically arranged on the frame and are rotatably connected to the frame.

[0010] A deceleration assembly is provided on one side of the frame to decelerate the guide wheel. The deceleration assembly includes a deceleration cylinder, a rotating body, and a sliding block. The rotating body is fixedly connected to the guide wheel, and the deceleration cylinder is fixedly installed on the frame. The rotating body is located inside the deceleration cylinder, and several slidable sliding blocks are provided on the side wall of the rotating body. The sliding blocks can abut against the inner wall of the deceleration cylinder.

[0011] In a preferred embodiment of this invention, the deceleration assembly further includes a magnet, which is movably disposed within the rotating body and provides an attractive force to the sling block toward the center of the rotating body.

[0012] In a preferred embodiment of this invention, the rotating body forms a cylindrical structure, and the end of the rotating body is fixedly connected to the end of the guide wheel.

[0013] In a preferred embodiment of this utility model, the circumferential surface of the rotating body is provided with a plurality of sliding grooves adapted to the throwing blocks, and the throwing blocks are slidably disposed in the sliding grooves.

[0014] In a preferred embodiment of this utility model, the deceleration assembly further includes deceleration columns, the deceleration cylinder is formed into a cylinder, and a plurality of deceleration columns are equidistantly arranged on the inner wall of the deceleration cylinder, the deceleration columns being semi-circular columns.

[0015] In a preferred embodiment of this utility model, the deceleration assembly further includes an adjusting screw, which is fixedly connected to a magnet. The end of the deceleration cylinder is provided with a threaded hole, and the adjusting screw is threadedly connected to the threaded hole at the end of the deceleration cylinder.

[0016] In a preferred embodiment of this utility model, the gripper assembly further includes an installation channel and ribs. The top and side walls of the frame are provided with installation channels. Bolts pass through the installation channels and lock with the installation holes of the mounting base. Several ribs are fixedly provided on the side of the frame near the mounting base. Several thrust grooves adapted to the ribs are provided on the side wall of the mounting base. The ribs can be inserted into the thrust grooves.

[0017] An attached lifting scaffold includes a scaffold body, a guide rod fixedly provided on one side of the scaffold body, and all of the above-mentioned wall-mounted guide seats provided on one side of the guide rod. The guide rod is located between two guide wheels of the same frame.

[0018] This utility model provides a wall-mounted guide seat and an attached lifting scaffold. It has the following beneficial effects:

[0019] 1. This wall-mounted guide seat and attached lifting scaffold uses a guide wheel to drive a rotating body to rotate within a reduction cylinder. When the guide wheel moves slowly on the surface of the guide rod, the attraction of the magnet to the throwing block is greater than the centrifugal force generated by the rotation of the rotating body. Consequently, the throwing block is located inside the slide groove. When a fall occurs, the rotation speed of the guide wheel increases, and the centrifugal force generated by the rotation of the rotating body is greater than the attraction of the magnet to the throwing block. Consequently, the throwing block is thrown out by the rotating body and comes into contact with each reduction column. The resistance against the rotation of the guide wheel is generated by the end of the throwing block squeezing the reduction column. The rolling friction between the guide wheel and the guide rod is changed to sliding friction, which greatly improves the braking force between the guide wheel and the guide rod and suppresses the fall.

[0020] 2. This wall-mounted guide seat and attached lifting scaffold, by rotating the adjusting screw, drives the magnet to move within the rotating cavity, adjusts the distance between the magnet and each swing block, thereby controlling the attractive force of the magnet on the swing block, achieving control of the swing block's swing force, and adjusting and controlling the speed at which the swing block triggers braking, is highly adjustable and flexible.

[0021] 3. This type of wall-mounted guide seat and attached lifting scaffold, by setting an installation channel, allows bolts to pass through the installation channel and be locked with the mounting seat. The bolts can be used with nuts to press and fix the frame to the mounting seat. The installation channel can adjust the installation position of the frame while ensuring the stable connection between the frame and the mounting seat. In addition, the distance between the two sets of frames can be adjusted to adapt to the installation of the guide rods of the scaffold body.

[0022] 4. This wall-mounted guide seat and attached lifting scaffold, by setting cylindrical protruding ribs, can be embedded in the thrust groove when the frame and the mounting seat are tightly fitted, thereby ensuring the thrust resistance between the frame and the mounting seat. It can adjust the installation position of the frame before the bolts are fully tightened, and can also ensure the stability of the frame after the bolts are locked. Attached Figure Description

[0030] A wall-mounted guide seat and an attached lifting scaffold, such as Figure 1 As shown, it includes:

[0031] The main body 10 has a mounting base 11 fixedly installed on one side.

[0032] like Figure 2 and Figure 3 As shown, the gripper assembly is detachably mounted on one side of the mounting base 11 and has two sets. The two sets of gripper assemblies are symmetrically distributed and the spacing can be adjusted. The gripper assembly includes a frame 12 and guide wheels 13. The frame 12 is locked to the mounting base 11 by screws. Two guide wheels 13 are symmetrically arranged on the frame 12 and are rotatably connected to the frame 12. The guide rod is clamped by the two symmetrical guide wheels 13 on the same frame 12, which can ensure the stability and non-deviation of the scaffold body during the lifting process. The main body 10 can be fixed to the wall by bolts. The detachable frame 12 can facilitate later inspection and maintenance.

[0033] like Figure 3 As shown, the gripper assembly also includes an installation channel 14 and ribs 15. The top and side walls of the frame 12 are provided with installation channels 14. Bolts pass through the installation channels 14 and lock with the installation holes of the mounting base 11. Several ribs 15 are fixedly provided on the side of the frame 12 near the mounting base 11. Several thrust grooves adapted to the ribs 15 are provided on the side wall of the mounting base 11. The ribs 15 can be inserted into the thrust grooves.

[0034] By setting up the installation channel 14, bolts are passed through the installation channel 14 and locked with the mounting base 11. The bolts can be used with nuts to press and fix the frame 12 and the mounting base 11 together. The installation channel 14 can adjust the installation position of the frame 12 while ensuring the stable connection between the frame 12 and the mounting base 11. In this way, the distance between the two sets of frames 12 can be adjusted to adapt to the installation of the guide rods of the scaffold body.

[0035] To enhance the thrust resistance between the frame 12 and the mounting base 11, a cylindrical rib 15 is provided. When the frame 12 and the mounting base 11 are tightly fitted, the rib 15 can be embedded in the thrust groove, thereby ensuring the thrust resistance between the frame 12 and the mounting base 11. This allows for adjustment of the installation position of the frame 12 before the bolts are fully tightened, and also ensures the stability of the frame 12 after the bolts are tightened.

[0036] like Figure 4 , Figure 5 and Figure 6As shown, a deceleration assembly is disposed on one side of the frame 12 for decelerating the guide wheel 13. The deceleration assembly includes a deceleration cylinder 20, a rotating body 21, and sliding blocks 22. The rotating body 21 is fixedly connected to the guide wheel 13, and the deceleration cylinder 20 is fixedly installed to the frame 12. The rotating body 21 is located inside the cylinder 20. Several slidable sliding blocks 22 are disposed on the side wall of the rotating body 21. The sliding blocks 22 can abut against the inner wall of the cylinder 20. The deceleration assembly also includes a magnet 24, which is movably disposed on the rotating body 20. Inside the body 21, the magnet 24 can provide an attractive force to the throwing block 22 towards the center of the rotating body 21. The rotating body 21 forms a cylindrical structure. The end of the rotating body 21 is fixedly connected to the end of the guide wheel 13. The circumferential surface of the rotating body 21 is provided with several sliding grooves adapted to the throwing block 22. The throwing block 22 is slidably disposed in the sliding grooves. The deceleration assembly also includes deceleration columns 23. The deceleration cylinder 20 forms a cylinder. Several deceleration columns 23 are equidistantly arranged on the inner wall of the deceleration cylinder 20. The deceleration columns 23 are semi-circular columns.

[0037] In this design, the guide wheel 13 rotates, driving the rotating body 21 to rotate within the reduction cylinder 20. When the guide wheel 13 moves slowly on the surface of the guide rod, the attraction force of the magnet 24 on the throwing block 22 is greater than the centrifugal force generated by the rotation of the rotating body 21. Consequently, the throwing block 22 is located inside the groove. When a fall occurs, the rotation speed of the guide wheel 13 increases, and the centrifugal force generated by the rotation of the rotating body 21 is greater than the attraction force of the magnet 24 on the throwing block 22. Consequently, the throwing block 22 is thrown out by the rotating body 21 and comes into contact with each reduction column 23. The resistance to the rotation of the guide wheel 13 is generated by the end of the throwing block 22 squeezing the reduction column 23. The rolling friction between the guide wheel 13 and the guide rod is changed to sliding friction, which greatly improves the braking force between the guide wheel 13 and the guide rod and suppresses the fall. The outer layer of the guide wheel 13 is covered with wear-resistant rubber (Shore A80 hardness), and the inner layer is an aluminum alloy hub, which reduces noise and enhances impact resistance. The braking performance under static friction is also guaranteed.

[0038] like Figure 5 and Figure 6 As shown, the deceleration assembly also includes an adjusting screw 25, which is fixedly connected to the magnet 24. The end of the deceleration cylinder 20 is provided with a threaded hole, and the adjusting screw 25 is threadedly connected to the threaded hole at the end of the deceleration cylinder 20. By rotating the adjusting screw 25, the adjusting screw 25 drives the magnet 24 to move within the cavity of the rotating body 21, thereby adjusting the distance between the magnet 24 and each swing block 22 and thus controlling the magnitude of the attraction force of the magnet 24 on the swing block 22, thereby controlling the swing force of the swing block 22. The speed at which the swing block 22 triggers braking can be adjusted and controlled, with strong adjustability and high flexibility.

[0039] As shown in the figure, an attached lifting scaffold includes a scaffold body. A guide rod is fixedly provided on one side of the scaffold body. All of the above-mentioned wall-mounted guide seats are provided on one side of the guide rod. The guide rod is located between two guide wheels 13 of the same frame 12. By setting the above-mentioned wall-mounted guide seats, the frame 12 can be flexibly adjusted to adapt to the guide rod. Secondly, it can also help to decelerate and prevent falls.

[0040] The working principle of this utility model is as follows: The main body 10 is locked and fixed to the wall using bolts. The guide rod of the scaffold body is clamped by two symmetrical guide wheels 13 passing through the same frame 12, ensuring stability and preventing deviation during the lifting and lowering of the scaffold body. An installation channel 14 is provided, through which bolts are passed and locked to the mounting base 11. Bolts can be used with nuts to press and fix the frame 12 and mounting base 11 together. The installation channel 14 allows adjustment of the frame 12's installation position while ensuring a stable connection between the frame 12 and mounting base 11. This allows for adjustable spacing between the two sets of frames 12 to accommodate the installation of the guide rods of the scaffold body. To enhance the thrust resistance between the frame 12 and mounting base 11, cylindrical ribs 15 are provided. When the frame 12 and mounting base 11 are tightly fitted, the ribs 15 can be embedded in the thrust groove, thus ensuring the thrust resistance between the frame 12 and mounting base 11. The rotation of the guide wheels 13 drives the rotating body... 21 rotates inside the reduction cylinder 20. When the guide wheel 13 moves slowly on the surface of the guide rod, the attraction of the magnet 24 to the throwing block 22 is greater than the centrifugal force generated by the rotation of the rotating body 21. As a result, the throwing block 22 is located inside the slide groove. When a fall occurs, the rotation speed of the guide wheel 13 increases, and the centrifugal force generated by the rotation of the rotating body 21 is greater than the attraction of the magnet 24 to the throwing block 22. As a result, the throwing block 22 is thrown out by the rotating body 21 and comes into contact with each reduction column 23. The resistance to the rotation of the guide wheel 13 is generated by the end of the throwing block 22 squeezing the reduction column 23. The rolling friction between the guide wheel 13 and the guide rod is changed to sliding friction, which greatly improves the braking force between the guide wheel 13 and the guide rod. The adjusting screw 25 is rotated, and the adjusting screw 25 drives the magnet 24 to move in the cavity of the rotating body 21. The distance between the magnet 24 and each throwing block 22 is adjusted, thereby controlling the magnitude of the attraction of the magnet 24 to the throwing block 22. This achieves the control of the throwing force of the throwing block 22. The speed at which the throwing block 22 triggers braking is adjusted and controlled.

[0041] It should be noted that the frame 12 is also equipped with a fall protection component disclosed in CN217680402U. The fall protection component includes a tension spring, a trigger swing block, a torsion spring, and a fall protection swing block. The torsion spring, the fall protection swing block, and the trigger swing block are coaxially arranged, with one end of the trigger swing block embedded in the trigger swing block and the other end pressing against the guide rail. One end of the torsion spring presses against the trigger swing block and the other end of the torsion spring presses against the fall protection swing block, so that the trigger swing block and the fall protection swing block form an acute angle. The end of the trigger swing block located in the fall protection swing block presses against the fall protection swing block, so that the acute angle between the two only decreases and does not increase. One end of the tension spring is connected to the end of the fall protection swing block near the C-shaped connector, and the other end is connected to the main body. A limit shaft is provided on the main body.

[0042] The anti-fall principle of the anti-fall component is as follows: during the upward movement of the frame, the guide rail only contacts the triggering swing block and pushes the triggering swing block to rise, without triggering the rotation of the anti-fall swing block;

[0043] During the descent of the frame, the guide rail moves down relative to the wall-mounted guide seat. The guide rail will contact the trigger swing block and lift the trigger swing block, while driving the anti-fall swing block to swing clockwise. However, due to the slow descent speed of the frame, the anti-fall swing block has enough time to reset under the push of the torsion spring.

[0044] When the frame falls, the guide rail drops rapidly, causing the trigger swing block to sink quickly. At the same time, the anti-fall swing block also sinks in a very short time. Due to the setting of the limit shaft, the anti-fall swing block is limited, causing the crossbar of the guide rail to press against the top of the anti-fall swing block. The anti-fall swing block cannot reset, and the guide rail cannot continue to move down, thus achieving the anti-fall effect.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
