Description

Technical Field

[0001] This utility model belongs to the field of construction site safety technology, and specifically relates to a protective device for a suspended platform limit device. Background Technology

[0002] On construction sites, especially high-rise building construction sites, exterior facade work extensively utilizes suspended scaffolds. These scaffolds are equipped with multiple limit devices for safety, and the reliability of each limit device must be guaranteed at all times during scaffold operation. Because workers may accidentally activate these devices during daily operations, and mortar and other adhesive materials can frequently trigger or affect the performance of the limit devices, protective devices for the scaffold limit devices are particularly necessary.

[0003] Existing common suspended platform limit devices, especially anti-overhead limiters, are all in an exposed state to ensure that the limit devices can be triggered in a timely manner. In daily use, especially in exterior wall painting operations, there are often uncured mortar falling from a height and triggering the limit devices, causing the suspended platform to stop suddenly or mortar to accumulate and stick to the limit device button, causing the limit devices to fail and affecting the safety of construction operations.

[0004] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and to provide a basket limit device protector.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A protective device for a suspended platform limit switch, comprising:

[0008] A steel plate channel, wherein the inner channel of the steel plate channel is adapted to a limiting device, the limiting device is installed at one end of the steel plate channel, the limiting device extends along the length direction of the steel plate channel, and the actuating shaft of the limiting device extends toward the end face of the steel plate channel;

[0009] A protective plate is provided on both sides of the protective plate, which is adapted to the cross-section of the inner groove of the steel plate groove. The protective plate is provided with wing plates corresponding to the limit device actuation shaft, and is slidably assembled in the inner groove of the steel plate groove along the length direction of the steel plate groove.

[0010] A buffer spring is sleeved on the actuating shaft of the limiting device, with its two ends abutting against the protective plate and the limiting device respectively, so that a buffer gap is formed between the protective plate and the actuating shaft of the limiting device.

[0011] A corresponding limiting device is provided on the travel path of the suspended platform to stop the work station. The steel plate groove is connected to the suspended platform and faces the stopping work station. In response, the steel plate groove abuts the stopping work station as the suspended platform moves, and the protective plate triggers the actuating shaft of the limiting device after overcoming the elasticity of the buffer spring.

[0012] Preferably, the steel plate groove has strip-shaped holes extending along its length on both sides, and the wing plate is slidably assembled in the strip-shaped holes by means of a pin.

[0013] Preferably, the width of the wing plate is adapted to the width of the side wall of the steel plate groove, and a limiting strip corresponding to the wing plate is provided on the side wall of the steel plate groove.

[0014] Preferably, the limiting strip is integrally formed with the steel plate groove, and the wing plate is limited by bending towards the opening of the steel plate groove.

[0015] Preferably, the bottom of the steel plate groove is provided with multiple waist-shaped holes, and the limiting device is assembled in the waist-shaped holes by bolts.

[0016] Preferably, the protective plate is provided with protective plates extending toward the actuating shaft of the limiting device on both the upper and lower sides.

[0017] Preferably, the steel plate channel is fixed to the suspended platform by welding or bolts.

[0018] Beneficial effects: The protective plate and the wing plates on both sides protect the trigger shaft of the limit device, preventing it from being misoperated after it extends out of the basket. During the construction of the basket, it can effectively prevent mortar and other adhesives falling from the height from triggering the limit device and affecting its operation. In addition, the buffer spring can quickly reset and maintain its original functionality after being affected by falling objects. Attached Figure Description

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0028] like Figure 1-4As shown, a protective device for a suspended platform limiter includes a steel plate groove 1, a protective plate 6, and a buffer spring 10. The steel plate groove 1 is made of galvanized steel plate and is formed by bending sheet metal. The steel plate groove 1 has a square inner groove. The limiter is a trigger switch. Generally, the main body of the limiter 2 is square. Therefore, the shape of the inner groove of the steel plate groove 1 is adapted to the limiter 2. Specifically, the inner groove of the steel plate groove 1 is larger than the cross-section of the main body of the limiter 2. The limiter 2 is installed at one end of the steel plate groove 1 and extends along the length of the steel plate groove 1. The trigger shaft 3 of the limiter 2 extends toward the end face of the steel plate groove 1. The end face of the trigger shaft 3 should be on the same plane as the corresponding end face of the steel plate groove 1, or slightly protrude 0.5-3cm beyond the corresponding end face of the steel plate groove 1. This ensures that the protective plate 6 is triggered before it is fully slid into the steel plate groove 1, thus ensuring the limiter is in place. 2. It can be accurately and timely triggered. The protective plate 6 is adapted to the inner groove cross section of the steel plate groove 1. The protective plate 6 is provided with corresponding limit device 2 trigger shaft 3 wing plates 5 on both sides. The wing plates 5 are close to the inner walls on both sides of the steel plate groove 1, thereby protecting the limit device 2 and preventing the falling mortar from triggering the trigger shaft 3. This allows the protective plate 6 to be slidably assembled in the inner groove of the steel plate groove 1 along the length direction of the steel plate groove 1. When triggering is required, it can be slid towards the limit device 2 to trigger. The buffer spring 10 is correspondingly sleeved on the trigger shaft 3 of the limit device 2. The outer diameter of the buffer spring 10 is larger than that of the trigger shaft 3. The two ends of the buffer spring 10 abut against the protective plate 6 and the limit device 2 respectively, so that a buffer gap is formed between the protective plate 6 and the trigger shaft 3 of the limit device 2. Thus, after the mortar falls, the impact force is on the buffer spring 10, and the buffer gap prevents accidental triggering.

[0029] In practical use, a corresponding stop position for the limiting device 2 is set on the travel path of the suspended platform. The stop position is generally set above or below the suspended platform, usually a baffle or block fixed on the support or building structure. The steel plate groove 1 is connected to the suspended platform and is generally directly opposite the stop position along the longitudinal direction, either upward or downward. The steel plate groove 1 is fixed to the suspended platform by welding or bolts. As the suspended platform moves up and down, the steel plate groove 1 moves closer to and abuts the stop position. After the protective plate 6 overcomes the elasticity of the buffer spring 10, it touches the trigger shaft 3 of the limiting device 2, thereby triggering the device. The combination of the protective plate 6 and the buffer spring 10 reserves a buffer gap as a stroke, which can effectively prevent falling objects from accidentally triggering the limiting device 2, and can reset in time after being affected to avoid device failure. Under the protection of the protective plate 6, it can effectively prevent the accumulation of falling adhesives from affecting the normal triggering of the trigger point. In addition, the pin shaft 8 on the wing plate 5 of the protective plate 6 is installed at the sliding groove hole position on the wing plate 5 on both sides of the foundation unit, which can effectively limit the movement trajectory of the protective plate 6 and ensure practicality.

[0030] In this embodiment, the steel plate groove 1 is formed by stamping a 2mm thick hot-dip galvanized steel plate. The length of the steel plate groove 1 is 250mm, the bottom plate width is 104mm, the side wall width is 42mm, and the edge is rounded with a radius of 2mm. The protective plate 6 is also formed by stamping a 2mm thick hot-dip galvanized steel plate. Its main body size is 50mm×30mm, the size of the sliding shaft wing plates 5 on both sides is 69mm×28mm, the end is a semi-circular plate with a radius of 14mm, and the center of the circle is fixed with a pin 8. The size of the other two protective side plates is 30mm×32mm. The buffer spring 10 is a spring with a diameter of 24mm and a length of 60mm.

[0031] In an optional embodiment, the steel plate groove 1 has strip-shaped holes 9 extending along its length on both sides, and each of the two wing plates 5 is provided with a pin 8, which extends outward from the corresponding strip-shaped hole 9. The diameter of the pin 8 is 4mm, and the dimensions of the strip-shaped holes 9 on both sides are 74mm×4mm. This allows the wing plate 5 to be slidably assembled in the steel plate groove 1 via the pin 8. One end of the pin 8 extending out of the strip-shaped hole 9 is provided with a limiting flange, or the pin 8 can be a bolt that passes inward through the strip-shaped hole 9 and is threaded to the wing plate 5.

[0032] When the pin 8 is at the front end of the strip hole 9, there is a gap between the protective plate 6 and the trigger shaft 3, and at this time the buffer spring 10 is in a compressed state, so it has the driving force to drive the protective plate 6.

[0033] In an optional embodiment, an adjusting bolt is provided in the middle of the protective plate 6. The adjusting bolt passes through the protective plate 6 and points towards the trigger shaft 3, and there is a gap between the adjusting bolt and the trigger shaft 3, so that the compression gap of the protective plate 6 required for triggering can be adjusted according to the spring elasticity and the actual installation position.

[0034] In an optional embodiment, the width of the wing plate 5 is adapted to the width of the side wall of the steel plate groove 1. A limiting strip 4 corresponding to the wing plate 5 is provided on the side wall of the steel plate groove 1. The limiting strip 4 further limits the wing plate 5 at the opening of the steel plate groove 1 to ensure the running trajectory of the protective plate 6. The length and position of the limiting strip 4 are adapted to the strip hole 9.

[0035] The limiting strip 4 is integrally formed with the steel plate groove 1, and the wing plate 5 is limited by the sheet metal stamping and bending through the opening in the steel plate groove 1.

[0036] The bottom of the steel plate trough 1 is provided with multiple oblong holes 11. The limiting device 2 is bolted into the oblong holes 11, thereby allowing the limiting device 2 to be assembled and its position adjusted, ensuring that the actuating shaft 3 of the limiting device 2 can extend out of the end face of the steel plate trough 1. Furthermore, the bottom plate of the steel plate trough 1 is provided with four 36mm×5mm oblong holes 11 for the limiting device 2.

[0037] In an optional embodiment, the upper and lower sides of the protective plate 6 are provided with protective plates 7 that extend towards the actuating shaft 3 of the limiting device 2. The width of the protective plate 7 is adapted to the width of the steel plate groove 1. The entire protector has few constituent units, a simple working principle, can be reused multiple times, and is highly durable.

[0038] In an optional embodiment, one of the limiting strips 4 is hinged with an iron cover plate, and the other limiting strip 4 is provided with a magnetic buckle corresponding to the cover plate, thereby protecting the main body of the limiting device 2.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
