Description

Technical Field

[0001] This utility model belongs to the field of elevator shaft construction technology, specifically relating to an elevator shaft folding and telescopic inspection work platform. Background Technology

[0002] The elevator shaft folding telescopic work platform is a high-efficiency load-bearing device specifically designed for elevator shaft construction and maintenance. Through its hinged folding structure and telescopic adjustable design, it achieves rapid installation, spatial adaptability, and safe operation. It is used for wall construction (such as formwork installation and concrete pouring), equipment maintenance, and acceptance operations within the elevator shaft, replacing traditional steel pipe scaffolding. By folding and shrinking, it reduces volume, making it easy to hoist and store, and it is adaptable to different shaft sizes.

[0003] In some existing technologies, after the main support structure is basically installed, multiple treads are placed on two base supports to form a platform for workers to stand and walk on. However, there is no positional constraint on the treads; they are simply laid on the base supports. This can cause the treads to shift or even slip due to workers walking on them or tools hitting them, posing a safety hazard. At the same time, the vibrations generated by workers walking on the unrestrained treads during construction can cause relative friction between the treads and the supports. Over time, this may cause structural wear and shorten the service life.

[0004] Therefore, this utility model proposes an elevator shaft folding and telescopic inspection work platform that limits the placement of the pedal to prevent displacement during operation. Utility Model Content

[0005] To address the problem of potential displacement of the pedals during operation in existing technologies, this utility model provides a folding and telescopic inspection platform for elevator shafts.

[0006] The present invention adopts the following technical solution: a folding and telescopic inspection platform for elevator shafts, comprising a set of columns and a set of brackets respectively connected to them by bolts, wherein a pedal is placed on the top of the brackets and a set of limiting components is provided on the top of the brackets;

[0007] The limiting component includes a fixed rod that can slide vertically and reset. A locking block is connected to the top of the fixed rod via a bearing. When the pedal is placed to align with the limiting component, the connecting parts at both ends of the bottom of the pedal abut against the locking block and move, causing the locking block to rotate, reducing friction between the two. When the locking block engages with the slots opened on the connecting parts to complete the engagement, the position of the pedal is constrained.

[0008] Preferably, the limiting member further includes a fixing seat fixedly connected to the top of the bracket, a spring fixedly connected to the bottom of the inner wall of the fixing seat, a connecting plate fixedly connected to the top of the spring, and the end of the connecting plate away from the spring fixedly connected to the fixing rod.

[0009] Preferably, the end of the fixing rod away from the connecting plate passes through the top of the connecting seat and is slidably connected to the connecting seat.

[0010] Preferably, the spring is slidably engaged with the inner wall of the fixed seat, and the bearing is located at the end of the fixed rod away from the connecting plate.

[0011] Preferably, the top of the card block is curved.

[0012] Preferably, the connector is fixedly connected to the bottom of the pedal, and the end of the slot near the limiting member is provided with an inclined arc surface.

[0013] Preferably, the top of the card slot is adapted to the card block.

[0014] Beneficial effects:

[0015] (1) The elevator shaft folding telescopic inspection platform of this utility model uses the cooperation of the limiting part and the connecting part to make the card block and the card slot engage, so that the pedal is locked after placement, reducing installation time and avoiding the displacement of the pedal that may cause safety hazards. When the card block and the inclined surface of the card slot abut against each other, the card block can rotate under the action of the bearing, reducing the friction coefficient between the card block and the side wall of the card slot and extending the insertion and removal life.

[0016] (2) The elevator shaft folding telescopic inspection platform described in this utility model uses the elastic contact of the spring to change the engagement between the card block and the card slot from rigid collision to flexible contact, thereby reducing local stress concentration and avoiding metal fatigue.

[0017] (3) In the elevator shaft folding telescopic inspection platform described in this utility model, when the top of the card block first abuts against the inclined arc surface of the card slot, the spring is released with a clear "click" sound when the pedal is installed in place, and at the same time, there is a noticeable drop in the hand, which helps the operator to confirm the locking status in the dim shaft.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Example: Figures 1-6 The elevator shaft folding and telescopic inspection work platform shown includes a set of columns 1 and a set of brackets 2 connected to them by bolts. A pedal 3 is placed on the top of the bracket 2, and a set of limiting members 4 are provided on the top of the bracket 2. The limiting member 4 includes a fixed rod 44 that can slide vertically and can be reset. The top of the fixed rod 44 is connected to a locking block 46 through a bearing 45. When the pedal 3 is placed to align with the limiting member 4, the connecting parts 5 at both ends of the bottom of the pedal 3 abut against and move with the locking block 46, causing the locking block 46 to rotate, reducing the friction between the two. When the locking block 46 cooperates with the slot 51 opened on the connecting part 5 to complete the locking, the position of the pedal 3 is constrained.

[0027] In this embodiment, the lower end of the column 1 is bolted to one end of the bracket 2. A foldable diagonal rod forms a triangle between the column 1, bracket 2, and diagonal rod. After the base bracket 2 is installed, the pedal 3 is placed on the bracket 2. When placing the pedal 3, it cannot be guaranteed that the locking block 46 can be directly inserted into the slot 51. It should be placed as close as possible to the middle of the two brackets 2. If the locking block 46 engages perfectly with the slot 51 after the pedal 3 is placed, and the pedal 3 cannot move horizontally on top of the bracket 2 when moved, it indicates that the pedal 3 is properly positioned. If the locking block 46 cannot directly engage with the slot 51, it indicates that the pedal 3 is properly positioned. When the pedal 3 engages with the slot 51, the top of the locking block 46 will first abut against the inclined arc surface of the slot 51, and the pedal 3 will move slightly to help the locking block 46 engage with the slot 51. Under compression, the spring 42 is compressed. At the same time, during the movement of the pedal 3, the locking block 46 rotates on the fixed rod 44 through the bearing 45. When the locking block 46 is aligned with the slot 51 on the connector 5, the compressed spring 42 is released, pushing the locking block 46 into the top of the slot 51, completing the engagement of the locking block 46 and the slot 51, so that the pedal 3 will not be displaced due to the operator walking or normal touching.

[0028] Specifically, such as Figures 2-5As shown, the limiting component 4 also includes a fixed seat 41 fixedly connected to the top of the bracket 2. A spring 42 is fixedly connected to the bottom of the inner wall of the fixed seat 41, and a connecting plate 43 is fixedly connected to the top of the spring 42. The end of the connecting plate 43 away from the spring 42 is fixedly connected to the fixed rod 44. The end of the fixed rod 44 away from the connecting plate 43 passes through the top of the connecting seat and is slidably connected to the connecting seat. The spring 42 is slidably engaged with the inner wall of the fixed seat 41, and the bearing 45 is located at the end of the fixed rod 44 away from the connecting plate 43. The top of the locking block 46 is set with an arc surface. After the column 1 and the bracket 2 are installed, select the pedal 3 that matches the two brackets 2, and place the pedal 3 on the two brackets 2 in sequence, so that the side of the pedal 3 is in contact with the two columns 1. During the process of aligning the slot 51 and the locking block 46, move the pedal 3 close to the column 1. The arc end of the locking block 46 abuts against the inclined arc surface of the slot 51. At this time, the locking block 46 The pedal 44 rotates under the action of bearing 45. At the same time, under the gravity of the pedal 3, the spring 42 at the bottom of the fixing rod 44 is compressed, causing the fixing rod 44 and the locking block 46 to move down as a whole. When the locking block 46 is aligned with the locking slot 51, the spring 42 is released, pushing the locking block 46 to move up and insert into the locking slot 51 to complete the engagement. At this time, the position of the pedal 3 is limited, preventing it from moving horizontally on the top of the bracket 2, thus improving the safety of the operator during the operation. The pedal 3 is compatible with the two brackets 2. When the pedal 3 is moved close to the side wall of the column 1, when the locking block 46 engages with the locking slot 51, only two locking blocks 46 and two locking slots 51 will be engaged at the same time. When the spring 42 is released, a clear "click" sound can be heard, indicating that the engagement is complete. When placing the pedal 3 in the future, it should be kept close to the side of the previous pedal 3 to ensure that the two locking blocks 46 can engage with the corresponding locking slots 51 at the same time.

[0029] Specifically, the fixed rod 44 only moves vertically up and down under the restriction of the connecting plate 43. When the pedal 3 is placed on the top of the bracket 2, the connecting piece 5 abuts against the top of the locking block 46. The locking block 46 and the fixed rod 44 move downward under the pressure. At the same time, since the bearing 45 is provided between the fixed rod 44 and the locking block 46, when the inclined curved surface on the connecting piece 5 abuts against the arc surface at the top of the locking block 46 and moves, the spring 42 makes the arc end of the locking block 46 always abut against the inclined curved surface of the slot 51. The locking block 46 rotates on the fixed rod 44, thus reducing the coefficient of friction between the locking block 46 and the side wall of the slot 51 and avoiding direct rigid friction between the locking block 46 and the side wall of the slot 51.

[0030] Specifically, such as Figure 4 and Figure 6As shown, the connector 5 is fixedly connected to the bottom of the pedal 3, and the end of the slot 51 near the limiting member 4 is provided with an inclined arc surface; the top of the slot 51 is adapted to the block 46; the slot 51 consists of two parts, the upper end is adapted to the block 46, and the lower end is a frustum shape with a diameter that gradually increases from top to bottom, and its inclined arc surface contacts the arc end of the block 46 to assist the block 46 in engaging with the slot 51.

[0031] Working principle: In use, the column 1 and the bracket 2 are connected by bolts and diagonal rods. Multiple pedals 3 are placed on two brackets 2 in sequence. When placing the pedals 3, the connecting piece 5 at the bottom of the pedal 3 contacts the limiting piece 4 at the top of the bracket 2. For example, the arc end of the locking block 46 abuts against the inclined arc surface of the locking groove 51. When the pedal 3 is moved while it is pressed against the side wall of the column 1, the spring 42 is compressed due to the weight of the pedal 3, causing the connecting plate 43, the fixing rod 44, and the locking block 46 to move downward. During this process, the arc end of the locking block 46 remains in contact with the side wall of the column 1. The inclined arc surface of the slot 51 abuts against the slot 46, and the slot 46 rotates under the action of the bearing 45. When the slot 51 moves to the position of the slot 46, the spring 42 is released, pushing the connecting plate 43, the fixing rod 44 and the slot 46 to move upward, so that the two slots 46 are simultaneously locked into the upper end of the two slots 51. At this time, the pedal 3 cannot move horizontally at the top of the bracket 2, thus completing the limit of the pedal 3. Similarly, the other pedals 3 can be installed. When disassembling the pedal 3, simply move the pedal 3 upward to separate the slot 51 from the slot 46.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
