Description

Technical Field

[0001] The utility model relates to the field of climbing tools, in particular to an escalator stabilizing device. Background Art

[0002] A Chinese patent with publication number CN203161068U discloses a ladder anti-slip rack, which includes a hanging body for the ladder to lean on. Baffles are provided on both sides of the hanging body to prevent the ladder from shaking left and right when leaning on it. The hanging body is provided with an anti-slip component that contacts the ladder, and a protrusion that can be embedded in the eaves drainage groove is protruded on the side of the hanging body facing away from the anti-slip component.

[0003] When the above-mentioned anti-slip frame is used, since the escalator has to rely on the anti-slip frame, it is necessary to first set up the anti-slip frame on the drainage trough. The specific process is as follows: people need to first find the location where they need to climb, then set up the escalator nearby and climb up, embed the anti-slip frame into the climbing position, then get off the escalator, move the escalator to match the anti-slip frame, and then actually start climbing to work. When dismantling, it is also necessary to first move the escalator to a nearby location, and then climb up the escalator to remove the anti-slip frame. Therefore, the use process of the above-mentioned escalator anti-slip frame is relatively cumbersome and inconvenient. Utility Model Content

[0004] In view of the disadvantage that the existing ladder anti-slip frame needs to be erected before the ladder, which makes it inconvenient to go up and down the ladder repeatedly, the purpose of the utility model is to provide an escalator stabilizing device that can be installed after the escalator is erected.

[0005] In order to solve the above technical problems, the present invention is solved by the following technical solutions:

[0006] An escalator stabilizing device includes a shell, which is provided with a connecting portion capable of fixing the shell to a drainage trough, the connecting portion including a clamping assembly capable of clamping the side wall of the drainage trough, the clamping or loosening of the clamping assembly being controlled by an opening and closing assembly, a fastener is laterally protruded on the shell and capable of limiting the escalator from sliding laterally along the drainage trough or flipping away from the drainage trough, the fastener includes a fastening rod laterally penetrated through the shell, the fastening rod limits the escalator from flipping out of the drainage trough, the cross-section of the fastening rod is non-circular, and one end of the fastening rod is bent to form a limiting section that can cooperate with the shell to clamp one of the straight rods of the escalator from both sides.

[0007] By adopting the above scheme, when the escalator stabilizing device in this scheme is used, the escalator can be directly set up at the position where climbing is required, and then the operator climbs up the escalator with the escalator stabilizing device, first fastens the fastener with one of the vertical rods of the escalator, and at the same time aligns the loosened clamping assembly with the drainage trough. When the above steps are completed, the clamping assembly is driven by the opening and closing assembly to clamp the side wall of the drainage trough, and the escalator and the drainage trough are fixed at this time; compared with the existing technology, the escalator stabilizing device in this scheme can be directly climbed onto the escalator for installation, and does not need to be placed in advance, which reduces the number of operating steps; in terms of stability, the cooperation between the fastening section and the shell limits the left and right shaking of the escalator, and the fastening rod and the drainage trough cooperate to clamp the escalator in the middle, which limits the escalator from flipping over, and further increases the safety during climbing.

[0008] Preferably, an operating chamber for accommodating the connecting part and the limiting part is opened on the shell, and the clamping assembly includes a clamping block fixedly arranged on the shell and a rotating part rotatably arranged in the operating chamber. The rotating part can be flipped close to the clamping block and abut against it or move away from the clamping block, and the rotating part is connected to the opening and closing assembly.

[0009] Preferably, the opening and closing assembly includes an opening and closing handle rotatably arranged in the operating room and a connecting rod connected between the opening and closing handle and the rotating part. When the opening and closing handle is flipped away from the shell, the rotating part is driven away from the clamping block, and when the opening and closing handle is flipped close to the shell, the rotating part is driven close to the clamping block. The opening and closing handle is provided with a locking component for limiting the rotation of the opening and closing handle when the rotating part is close to the clamping block. The locking component includes an elastic card block telescopically arranged on the opening and closing handle, and a limiting groove for the elastic card block to be engaged is provided on the shell. The extension and retraction of the elastic card block is controlled by a pressing component.

[0010] The above-mentioned solution adopts the method of clamping the side wall of the drainage trough to install the escalator stabilizing device, and at the same time cooperates with the fasteners to limit the movement of the escalator. In the prior art, the escalator only relies on the hanging body. Therefore, in this solution, the connection between the escalator, the shell and the drainage trough is more reliable and safer.

[0011] Preferably, a first adjustment component is provided in the operating room for adjusting the length of the fastener extending out of the shell and limiting the movement of the fastener after adjustment.

[0012] With the above solution, the thickness of the two vertical rods of different types of escalators is different. In order to adapt to more types of escalators, this solution designs a fastener that can adjust the extension length.

[0013] Preferably, the first adjustment component includes a limit plate, which is provided with a through hole for the latching rod to pass through, and a movable gap is left between the through hole and the latching rod. A protrusion is provided on the side wall of the operating chamber away from the limiting section, and the upper end surface of the protrusion is recessed with a groove for the bottom part of the limit plate to be placed in. A first elastic member is provided between the limit plate and the side wall of the operating chamber, which drives the limit plate to flip away from the inner wall of the operating chamber with the part of itself abutting the groove as a fulcrum. When the limit plate flips, the edge of the through hole abuts against the latching rod to prevent the limit plate from continuing to flip.

[0014] By adopting the above scheme, due to the partial contact between the through hole and the latching rod, when the operator pulls the latching rod outward through the limiting section, the friction force generated between the latching rod and the limiting plate drives the limiting plate to move in the same direction as the latching rod, but the bottom of the limiting plate is limited by the groove, and can only make a flipping movement with the part of itself contacting the bottom of the recess. Therefore, when the operator pulls the latching rod outward, the limiting plate will flip downward. At this time, the friction between the inner wall of the through hole and the latching rod will limit the outward movement of the latching rod, and the elastic force of the first elastic member can continuously provide a flipping force to the limiting plate, so that the latching rod remains in a self-locking state and cannot be easily pulled out. When it is necessary to pull it outward, just pull the limiting plate toward the inner wall of the operating chamber so that the latching rod is in the gap between itself and the through hole. At this time, the friction between the latching rod and the inner wall of the through hole is reduced and it can be easily pulled out.

[0015] Preferably, both ends of the coupling rod are provided with limited segments, the coupling rod passes through both sides of the shell, and two groups of first adjustment components are symmetrically arranged in the operating room.

[0016] By adopting the above scheme, the first adjustment components are symmetrically arranged. Without pulling the limit plate, the extension or retraction of the coupling rod is restricted. The limiting effect is better than the situation in the previous scheme where only one set of first adjustment components is set. The design of setting limiting sections at both ends of the coupling rod enables both sides of the escalator stabilization device in this scheme to be connected to the vertical rods of the escalator, thereby improving versatility. When in use, a pair of the devices can be selected to fix the escalator.

[0017] Preferably, a second adjustment component capable of adjusting the distance between the fastener and the clamping assembly is provided in the operating room, the second adjustment component including a guide structure for connecting the fastener, a driving component for driving the fastener along the guide structure to approach the clamping assembly, and a reset component for driving the fastener along the guide structure to guide away from the clamping assembly.

[0018] Preferably, the guide structure includes a guide rail arranged on the inner wall of the operating chamber and a guide plate slidingly arranged on the guide rail, the fastener is arranged on the guide plate, a base plate is provided at one end of the guide rail close to the clamping assembly, and the reset component includes a second elastic member arranged between the base plate and the guide plate.

[0019] Using the above solution, taking into account the uneven heights of the eaves of the houses, the angles between the escalator and the wall when it is erected are inconsistent, which will cause the distance between the escalator and the gutter to change. The spacing between the connecting rod and the clamping assembly of this solution is adjustable, which can adapt to different usage scenarios, further increasing the applicability of the escalator stabilizing device.

[0020] Preferably, the driving component includes a stud arranged on the base plate and a pair of engaging nuts threadedly engaged with the stud, the engaging nuts including a first nut and a second nut, a pair of guide rods for guiding the second nut to move closer to or away from itself are arranged on both sides of the first nut, and a third elastic member for driving the first nut and the second nut to move away from each other and an adjusting member for driving the second nut to move closer to each other are arranged between the first nut and the second nut.

[0021] Preferably, the adjustment member includes a sliding plate slidingly arranged on the two guide rods, a limiting block is provided at the end of the guide rod, a fitting gap is left between the sliding plate and the limiting block, a limiting boss is partially protruded on the sliding plate and can fill the fitting gap, and a guide inclined surface is provided between the limiting boss and the sliding plate.

[0022] With the above solution, considering that the second adjustment assembly is completely arranged in the operating room and the operating space is relatively small, if an ordinary nut is used, at most only two fingers can smoothly contact the nut for adjustment, and the position of the nut can almost only be adjusted by turning the nut from one side. It takes at least 3 to 4 turns to make the nut turn one circle, and the adjustment is very slow. The present solution adopts an engaging nut. When the engaging nut is not unlocked, the limit boss presses against the limit block to fill the active gap. When unlocking, it is only necessary to turn the sliding plate to make the limit boss slide horizontally until it is separated from the limit block. The third elastic member drives the first nut and the second nut away from each other. At this time, the engaging nut can slide relative to the stud to achieve quick adjustment. When adjusted to the desired position, it is only necessary to pinch the first nut and the second nut from both sides to drive the two together. At the same time, the sliding plate can be turned and the guide bevel can be used to assist the first nut and the second nut to approach. When the limit boss refills the active gap between the sliding plate and the limit block, the locking is completed, which greatly reduces the time required to adjust the position of the buckle rod.

[0023] Due to the adoption of the above technical scheme, the present invention has significant technical effects: when the escalator stabilizer in the present scheme is used, the escalator can be directly set up at the position where climbing is required, and then the operator climbs up the escalator with the escalator stabilizer, first fastens the fastener with one of the vertical rods of the escalator, and at the same time aligns the clamping assembly in the loose state with the drainage trough. When the above steps are completed, the clamping assembly is driven by the opening and closing assembly to clamp the side wall of the drainage trough, and the escalator and the drainage trough are fixed at this time; compared with the existing technology, the escalator stabilizer in the present scheme can be directly climbed onto the escalator for installation, and does not need to be placed in advance, which reduces the number of operating steps; in terms of stability, the cooperation between the fastening section and the shell limits the left and right shaking of the escalator, and the fastening rod and the drainage trough cooperate to clamp the escalator in the middle, which limits the escalator from flipping over, and further increases the safety during climbing.

[0040] The present invention is described in further detail below with reference to the accompanying drawings and embodiments.

[0041] Example

[0042] An escalator stabilizing device, according to Figure 1 As shown, it includes a shell 1, and a connecting portion is provided on the shell 1 to fix the shell 1 to the drain trough. The connecting portion includes a clamping assembly that can clamp the side wall of the drain trough. Figure 1 、 2As shown in FIG5 , an operating chamber 4 for accommodating a connecting portion and a fastening member is provided on the shell 1. The clamping assembly includes a clamping block 5 fixedly provided on the shell 1 and a rotating member 6 rotatably provided in the operating chamber 4. The rotating member 6 can flip close to the clamping block 5 and abut against or away from the clamping block 5. The clamping or loosening of the clamping assembly is controlled by the opening and closing assembly. As shown in the figure, the opening and closing assembly includes an opening and closing handle 7 rotatably provided in the operating chamber 4 and a connecting rod 8 connected between the opening and closing handle 7 and the rotating member 6. When the opening and closing handle 7 is flipped away from the shell 1, the rotating member 6 is driven away from the clamping block 5. When the opening and closing handle 7 is flipped close to the shell 1, the rotating member 6 is driven close to the clamping block 5. A locking component is provided on the opening and closing handle 7 for limiting the rotation of the opening and closing handle 7 when the rotating member 6 is close to the clamping block 5. The locking component includes an elastic block 9 telescopically provided on the opening and closing handle 7. A limiting groove 10 for the elastic block 9 to be clamped in is provided on the shell 1. The extension and retraction of the elastic block 9 is controlled by a pressing member 11. Figure 3 As shown, in this embodiment, the pressing member 11 and the elastic block 9 are connected by a lever component 29. By pressing the pressing member 11, the elastic block 9 can be driven to retract into the opening and closing handle 7 through the lever component 29. When the pressing member 11 is released, the elastic force of the elastic block 9 drives itself to pop out of the opening and closing handle 7.

[0043] The housing 1 is laterally provided with a fastener that can limit the escalator from sliding laterally along the drainage trough or turning away from the drainage trough. Figure 1 、 6 As shown in Figure 8, the fastening member includes a fastening rod 2 that is transversely passed through the shell 1. The fastening rod 2 limits the escalator from flipping out of the drainage trough. The cross section of the fastening rod 2 is non-circular. One end of the fastening rod 2 is bent to form a limiting section 3 that can cooperate with the shell 1 to clamp one of the straight rods of the escalator from both sides. In this embodiment, both ends of the fastening rod 2 are provided with a limiting section 3. The fastening rod 2 passes through both sides of the shell 1. A first adjusting component for adjusting the length of the fastening member extending out of the shell 1 and limiting the movement of the fastening member after adjustment is provided in the operating room 4. Figure 7 、 9 As shown, the first adjustment component includes a limit plate 12, a through hole 13 is provided on the limit plate 12 for the buckle rod 2 to pass through, and a movable gap is left between the through hole 13 and the buckle rod 2, and a protrusion 14 is convexly provided on the side wall of the operating chamber 4 away from the limit section 3. The upper end surface of the protrusion 14 is recessed with a groove 15 for the bottom part of the limit plate 12 to be partially placed. A first elastic member 16 is provided between the limit plate 12 and the side wall of the operating chamber 4 to drive the limit plate 12 to flip away from the inner wall of the operating chamber 4 with the part of itself abutting against the groove 15 as a fulcrum. When the limit plate 12 flips, the edge of the through hole 13 abuts against the buckle rod 2 to prevent the limit plate 12 from continuing to flip. In this embodiment, two groups of first adjustment components are symmetrically arranged in the operating chamber 4.

[0044] The operating room 4 is provided with a second adjusting assembly capable of adjusting the distance between the fastener and the clamping assembly. The second adjusting assembly includes a guide structure for connecting the fastener. Figure 4 、 12 As shown, the guide structure includes a guide rail 17 provided on the inner wall of the operating room 4 and a guide plate 18 provided on the guide rail 17 for sliding movement. The fastener is provided on the guide plate 18. A bottom plate 19 is provided at one end of the guide rail 17 close to the clamping assembly. A second elastic member 20 is provided between the guide plate 18 and the bottom plate 19 to drive the fastener along the guide structure away from the clamping assembly. The second adjustment assembly also includes a driving component that drives the fastener along the guide structure to guide the fastener close to the clamping assembly. Figures 12-15 As shown, the driving component includes a stud 21 provided on the base plate 19 and a pair of engaging nuts 22 threadedly provided with the stud 21. The engaging nuts 22 include a first nut 221 and a second nut 222. A pair of guide rods 23 for guiding the second nut 222 to move closer to or away from itself are provided on both sides of the first nut 221. A third elastic member 24 for driving the first nut 221 and the second nut 222 to move away from each other and an adjusting member for driving the first nut 221 and the second nut 222 to move closer to each other are provided between them. Figure 13 、 15 As shown, in this embodiment, the adjustment member includes a sliding plate 25 slidingly arranged on two guide rods 23, a limiting block 26 is provided at the end of the guide rod 23, a movable gap is left between the sliding plate 25 and the limiting block 26, a limiting boss 27 that can fill the movable gap is partially protruded on the sliding plate 25, and a guide inclined surface 28 is provided between the limiting boss 27 and the sliding plate 25.

[0045] Combined with the above structure, reference Figures 1 to 15 It can be seen that the use process of a set of escalator stabilization devices in this example is as follows:

[0046] First, set up the escalator at the location where climbing is required, then carry the escalator stabilizer and climb up the escalator to the junction of the escalator and the gutter on the eaves, place the side wall of the gutter between the clamping block 5 and the rotating part 6, and at the same time align and buckle the fastener to the vertical rod part of the escalator, then turn the opening and closing handle 7 until the elastic block 9 is stuck in the limit groove 10. At this time, the rotating part 6 cooperates with the clamping block 5 to clamp the side wall of the gutter, thereby completing the fixation of one side of the escalator, and then repeat the above process on the other side to complete the fixation of both sides.

[0047] When the escalator stabilizing device in this embodiment is used, one can directly climb up the escalator to install it without the need for pre-placement, thus reducing the number of operation steps; in terms of stability, the cooperation between the buckle section and the shell 1 limits the left and right shaking of the escalator, and the buckle rod 2 cooperates with the drainage groove to clamp the escalator in the middle, limiting the escalator from flipping over, further increasing safety when climbing.

[0048] The second adjustment assembly of this embodiment adopts a locking method using an engaging nut 22. When the engaging nut 22 is unlocked, the limiting boss 27 presses against the limiting block 26 to fill the movable gap. To unlock, it is only necessary to move the sliding plate 25 to make the limiting boss 27 slide horizontally until it is free from the limiting block 26. The third elastic member 24 drives the first nut 221 and the second nut 222 away from each other. At this time, the engaging nut 22 can slide relative to the stud 21 to achieve rapid adjustment.

[0049] When the coupling rod 2 is adjusted to the desired position, it is only necessary to pinch the first nut 221 and the second nut 222 from both sides to drive the two together. At the same time, the sliding plate 25 can be moved and the guide bevel 28 can be used to assist the first nut 221 and the second nut 222 to move together. When the limiting boss 27 refills the movable gap between the sliding plate 25 and the limiting block 26, the locking can be completed, which greatly reduces the time required to adjust the position of the coupling rod 2.

[0050] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
