Description

Technical Field

[0001] The utility model relates to the technical field of wiping roller cleaning, in particular to a quick limiting device for a wiping roller moving trolley. Background Art

[0002] A linear circular (optical axis) guide rail is installed at the bottom of the wiping roller moving platform to facilitate the wiping roller personnel to move back and forth when cleaning the roller surface. The existing common technical solution is to add a locking structure to the linear circular (optical axis) guide rail slider and turn the locking slider by rotating the screw rod with a handle.

[0003] In actual use, the existing locking method requires manual use of a hand-twisted lead screw to rotate multiple times to lock the mobile platform. The operation is very inflexible, and due to the screw tightening method, the relative contact area is small and the friction is insufficient, so that when people walk on or move on the mobile platform, the platform will move. In addition, the locking position is located at the bottom of the mobile platform, which is not easy to operate and takes a long time to lock, and the purpose of fast locking cannot be achieved, thereby prolonging the cleaning time of the roller wiper and reducing the cleaning efficiency. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a quick limiting device for a wiping roller moving trolley, which changes the slider locking into a slide rail locking, and increases the contact area by replacing the locking block. The mobile platform can be quickly clamped and locked, thereby improving the cleaning efficiency of the wiping roller and reducing labor intensity.

[0005] The utility model is realized through the following technical solutions:

[0006] A quick limiting device for a wiping roller moving trolley is provided, comprising a limiting mounting plate, a mounting hole is provided at the lower front portion of the limiting mounting plate, and the limiting mounting plate is installed on the side of the wiping roller moving trolley and above the slide rail through mounting screws, a connecting hole is provided at the upper front portion of the limiting mounting plate, and a manual clamp is vertically connected to the plate through connecting screws, a pressure rod end of the manual clamp is connected to a pressure block that can cooperate with the pressure rod to move downward to contact and press the slide rail, a positioning groove perpendicular to the length direction of the slide rail is provided on the top surface of the pressure block, the positioning groove is convex in shape on the cross section of the pressure block and is open at the top, a fixing nut with the same width as the positioning groove is slidably embedded in the bottom surface of the positioning groove, the end of the pressure rod is a screw rod with a thread, the screw rod is threadedly connected to the fixing nut, and a locking nut is also threadedly connected to the surface of the pressure block on the screw.

[0007] Furthermore, a clamping groove is formed on the bottom surface of the clamping block, and the inner top surface of the clamping groove is an arc shape matching the shape of the slide rail.

[0008] The bottom surface of the clamping block is provided with a clamping groove for contacting and cooperating with the slide rail. By designing the inner top surface of the clamping groove to be an arc shape with the same shape as the slide rail, the contact area with the slide rail is increased, thereby ensuring the clamping effect.

[0009] Preferably, the pressing block is a pressing block made of a non-rigid material.

[0010] The clamping block is made of non-rigid material and maintains a certain elasticity with the slide rail. Firstly, it protects the slide rail from being crushed, and secondly, it can ensure the clamping effect.

[0011] Furthermore, a relief groove for evading the screw rod is formed in a recessed manner along the length direction of the bottom center line of the positioning groove.

[0012] An avoidance groove is arranged at the center of the bottom surface of the positioning groove, which can be used to avoid the screw rod, and the nut can be easily loosened and locked, and the position of the clamping block on the screw rod can be adjusted to facilitate the adjustment of the clamping force on the slide rail.

[0013] Furthermore, the manual clamp includes a base plate seat parallel to the limit mounting plate, a vertically arranged and C-shaped fixed seat is formed on the base plate seat, a guide sleeve for the pressure rod to pass through is formed at the lower part of the fixed seat, a hinged seat is formed at the upper part of the fixed seat and is rotatably connected to an L-shaped handle through a first pin shaft, the handle is hinged at the inflection point through a second pin shaft and has two symmetrically arranged connecting plates, and the lower ends of the two connecting plates are hinged to the upper end of the pressure rod located above the guide sleeve through a third pin shaft.

[0014] The manual clamp uses the position of the rotating handle and the connecting plate to apply force to the pressure rod. The pressure rod can be moved downward to drive the clamping block to complete the clamping positioning of the slide rail. In order to ensure the stability of the clamping, the manual clamp is designed with a self-locking function. When clamping, it is ensured that the second pin shaft does not fall onto the vertical connection line between the first pin shaft and the third pin shaft, so that the connecting plate is tilted and not perpendicular to the first pin shaft and the third pin shaft, so that the direction of the resultant force on the connecting plate is diagonally directed to the inside of the fixed seat.

[0015] Furthermore, a rubber anti-slip sleeve is provided on the handle.

[0016] By sleeve-connecting a rubber anti-slip sleeve on the handle, the friction with the palm can be increased, making it easier for the operator to operate the handle to complete positioning, locking or unlocking.

[0017] Beneficial effects of the utility model:

[0018] The limiting device designed by the utility model abandons the original locking device. A manual clamp is designed on the side of the wiping roller moving trolley to cooperate with a quick clamping assembly of the clamping block. The slider locking is changed to the slide rail locking. The clamping groove on the clamping block increases the contact area with the slide rail. The manual clamp is manually operated to complete locking and unlocking. The operation is convenient and fast, which can greatly shorten the clamping and locking time of the wiping roller moving trolley and at the same time improve the locking stability of the wiping roller moving trolley, which is convenient for operators to use when cleaning the wiping roller, improves the cleaning efficiency of the wiping roller and effectively reduces labor intensity.

DETAILED DESCRIPTION

[0025] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0026] A quick limiting device for a wiping roller moving trolley comprises a limiting mounting plate 1, a mounting hole is provided at the lower front portion of the limiting mounting plate 1 and is mounted on the side of the wiping roller moving trolley 2 and above the slide rail 4 through mounting screws, a connecting hole is provided at the upper front portion of the limiting mounting plate 1 and is vertically connected with a manual clamp through connecting screws, and a pressing block 18 is connected at the end of a pressure rod 14 of the manual clamp which can cooperate with the pressure rod 14 to move downward to contact and press the slide rail 4.

[0027] In this embodiment, the manual clamp includes a base plate seat 5 parallel to the limit mounting plate 1, and a vertically arranged and C-shaped fixed seat 13 is formed on the base plate seat 5. A guide sleeve 12 for a pressure rod 14 to pass through is formed at the lower part of the fixed seat 13. A hinged seat is formed at the upper part of the fixed seat 13 and is rotatably connected to an L-shaped handle 7 through a first pin shaft 6. In order to increase the friction of the handle 7 and facilitate the rotation of the handle 7, a rubber anti-slip sleeve 9 is sleeved and connected to the handle 7.

[0028] The handle 7 is hinged at the inflection point with two symmetrically arranged connecting plates 10 through the second pin 8, and the lower ends of the two connecting plates 10 are hinged to the upper end of the pressure rod 14 located above the guide sleeve 12 through the third pin 11. Figure 2As shown, in order to ensure the stability of positioning and locking, the manual clamp is provided with a self-locking function. By turning the handle 7, the connecting plate 10 driven by the handle 7 is tilted toward the inside of the fixing seat 13. When the handle 7 falls completely, the pressing block 18 will exert an oblique upward force. The direction of the combined force is as follows: Figure 2 As shown in F, the handle 7 is inclined inward along the length direction of the connecting plate 10, and the turning point of the handle 7 abuts against the inner side of the fixing seat 13. Since the inner side of the fixing seat 13 is in a closed state, the self-locking function can be realized, and it will not automatically bounce open due to the reaction force of the clamping block 18.

[0029] A positioning groove 20 perpendicular to the length direction of the slide rail 4 is provided on the top surface of the clamping block 18. The positioning groove 20 is convex in shape and open at the top on the cross section of the clamping block 18. A fixing nut 17 with the same width as the positioning groove 20 is slidably embedded in the bottom surface of the positioning groove 20. The end of the pressure rod 14 is a threaded screw 16, which is threadedly connected to the fixing nut 17. A locking nut 15 is also threadedly connected to the screw 16 on the surface of the clamping block 18.

[0030] The bottom surface of the clamping block 18 is concavely formed with a clamping groove 19, and the inner top surface of the clamping groove 19 is an arc shape matching the shape of the slide rail 4. In order to ensure the clamping protection of the slide rail 4, the clamping block 18 is formed of a non-rigid material, and a rubber block can be used, which can not only buffer the pressure reduction, but also increase the friction with the slide rail 4 to ensure the stability of the clamping.

[0031] The bottom midline of the positioning groove 20 is concavely formed with an escape groove along the length direction for escaping the screw 16. The escape groove is used to adjust the upper and lower positions of the pressing block 18 on the screw 16, and then the pressing force can be adjusted as needed. Of course, the depth of the positioning groove 20 can also be increased to ensure the upper and lower adjustment space of the screw 16.

[0032] The wiping roller moving trolley 2 is connected to the equipment through the slider 3 and the slide rail 4 to achieve forward and backward movement. When the worker is cleaning the roller surface, when cleaning is required at the designated position, the worker can turn the handle 7 of the manual clamp and use the pressure rod 14 of the manual clamp to drive the clamping block 18 to move downward, so that the clamping groove 19 of the clamping block 18 clamps and limits the slide rail 4. The wiping roller moving trolley 2 is respectively arranged front and back on both sides of the length direction of the slide rail 4, which can be manually positioned quickly and it is also convenient to release the limit. The limit release is completed by reversely operating the handle 7 of the manual clamp. The operation is convenient, the locking and unlocking time is short, and the cleaning work time is shortened.

[0033] Of course, the above description is not limited to the above examples. The technical features not described in the present invention can be achieved by or by adopting the existing technology, which will not be repeated here.
