Description

Technical Field

[0001] This application relates to the field of anchor bolt trolley technology, and more particularly to a slider structure used in a low-profile anchor bolt trolley pusher. Background Technology

[0002] As a primary piece of equipment for roadway support, the bolt trolley mainly provides support by inserting bolts into the roadway walls. Due to limited space in low-ceilinged roadways, low-profile bolt trolleys are necessary for support work. During the bolt insertion and drilling processes, a pusher is typically used. The pusher's range of motion is related to the size of the slider; the longer the slider, the smaller the effective sliding range of the pusher. Therefore, low-profile bolt trolleys should use sliders with the smallest possible dimensions.

[0003] Currently, a slider system consists of upper and lower pressure plates with identical structures. Each pair of pressure plates is bolted to a bracket. The bolt holes on the pressure plates are of the slanted groove type, allowing adjustment of the bracket on the propulsion beam by longitudinally moving the pressure plates. However, engaging the pressure plates requires at least two holes, and the slanted groove type holes take up space. Furthermore, longitudinal space must be maintained when adjusting the pressure plate tightness. Therefore, this slider structure is unsuitable for propellers with high requirements for longitudinal length. Thus, it is necessary to improve the existing slider structure. Utility Model Content

[0004] One objective of this application is to provide a slider structure for use on a low-profile anchor trolley pusher that can solve at least one of the defects in the aforementioned background art.

[0005] To achieve at least one of the above objectives, the technical solution adopted in this application is as follows: a slider structure for use on a low-profile anchor trolley pusher, comprising a slider body, wherein the slider is provided with two mutually inclined mounting portions, the two mounting portions cooperating to form a sliding cavity, and the slider is slidably mounted on a slide rail through the sliding cavity; the mounting portions are provided with mounting grooves, and a liner for sliding with the slide rail is installed in the mounting grooves; the slider is also provided with mounting shoulders, and the mounting shoulders are provided with multiple slots for mounting brackets, the multiple slots being arranged along the length direction of the slider, and an adjustment mechanism for adjusting the position of the slider is installed on the brackets.

[0006] With the above configuration, the slider can be designed as an integrated structure, giving it a higher resistance to torsional loads and making its rigidity far exceed that of a split slider. Furthermore, the integrated structure avoids the need for excessive fasteners on the slider, ensuring that only slots are provided on the mounting components, allowing for a smaller overall slider size. When the slider mates with the slide rail, the end face of the liner directly contacts the slide rail, further enhancing the safety of the slider and slide rail. If the liner is damaged, repairs can be quickly completed by simply removing it from the mounting slot and replacing it with a new one. The bracket can be fixedly connected to the slider via slots. When the liner wears or the slider's position deviates, the slider's position can be adjusted via an adjustment mechanism to ensure stable sliding on the slide rail.

[0007] Preferably, there are two sliders, each mounted on one side of the slide rail. This arrangement allows the two sliders to cooperate and provide support, and the width between the two sliding cavities matches the width of the guide rails on both sides, preventing the sliders from detaching from the slide rail.

[0008] Preferably, the mounting groove is provided with a limiting groove, and the liner is provided with a limiting block that mates with the limiting groove; fixing components are installed at both ends of the mounting groove. This configuration improves the installation stability of the liner through the limiting engagement of the limiting block and the limiting groove, allowing the liner to slide in a fixed direction within the mounting groove. During installation, simply aligning the limiting block with the limiting groove allows the liner to be inserted into the mounting groove, while the fixing components at both ends seal the liner, preventing relative sliding between the liner and the mounting groove during engagement with the slide rail.

[0009] Preferably, the fixing component includes a baffle, and mounting holes are provided at both ends of the slider. The baffle is fixedly installed to the slider by bolts, and the baffle is used to prevent the liner from dislodging from the mounting groove. This configuration can further improve the replacement efficiency of the liner. When the liner is damaged, simply loosen the bolts and remove the baffle to release the blockage on the liner. The user can then simply pull out the damaged liner and replace it.

[0010] Preferably, the liner protrudes from the mounting groove. This arrangement prevents the slider from directly contacting the slide rail. Since the liner is inexpensive and easy to replace, it effectively improves the service life of the slider and slide rail, and reduces the maintenance and repair costs of the slider.

[0011] Preferably, the angle between the two mounting portions on the same slider is 90°, and the connection between the two mounting portions is rounded. This configuration ensures that the angles of the mounting portions and the two guide surfaces of the guide rail are consistent, allowing the liner to fit tightly against the slide rail, improving the stability of the slider's sliding and reducing the wear rate of the liner.

[0012] Preferably, the liner is a nylon plate. This configuration further reduces the weight of the liner, and the nylon plate has self-lubricating properties, which can effectively reduce the friction between the liner and the slide rail; in addition, the nylon plate can also absorb the vibration and impact during the movement of the slider, preventing damage to the structure of the pusher.

[0013] Preferably, the liner has a cavity that communicates with the outside. This design reduces the amount of material used in the liner, lowering costs, and also optimizes the stress distribution on the liner, dispersing the pressure between the liner and the slide rail, thus preventing stress concentration at a single point on the liner and potential breakage.

[0014] Preferably, the slot is elongated. This design allows for fine-tuning of the bracket's position along the long side of the slot when adjustments to the slider's and bracket's mounting positions are needed, thereby improving the compatibility between the slider and bracket.

[0015] Preferably, the adjustment mechanism includes a set screw, and the side of the bracket is provided with a screw hole that mates with the set screw. The end of the set screw abuts against the side of the slider, and the set screw is used to adjust the position of the slider. With this configuration, when the liner wears, the position of the slider can be adjusted using the set screw, thereby adjusting the mating distance between the liner and the slide rail, ensuring that the slider can continue to slide stably on the slide rail after adjustment.

[0016] Compared with the prior art, the beneficial effects of this application are as follows: The slider features a one-piece structure, offering superior resistance to torsional loads and significantly higher rigidity compared to split-piece sliders. Furthermore, the integrated structure eliminates the need for numerous fasteners, ensuring only slots and holes are present on the mounting components, allowing for a smaller overall slider size. This design minimizes the space occupied by the slider on the pusher, making it more suitable for operation in low-ceilinged tunnels. A liner further enhances the safety of the slider and rail; damage to the liner is quickly repaired by simply removing it from its mounting slot and replacing it with a new one. An adjustment mechanism allows for precise adjustment of the slider's position to ensure stable sliding on the rail.

[0017] The limiting block and limiting groove's limiting fit improve the installation stability of the liner, allowing the liner to slide in a fixed direction. The plate prevents the liner from detaching from the mounting groove, avoiding relative sliding between the liner and the mounting groove during engagement with the slide rail. The cavity inside the liner reduces material usage and lowers costs; it also optimizes the stress distribution, dispersing pressure between the liner and the slide rail, preventing stress concentration at a single point and thus preventing liner breakage. This invention has advantages such as small size, stable structure, and long service life. Attached Figure Description

[0023] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] In the description of this application, it should be noted that the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., which indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of this application.

[0025] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0026] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0027] One aspect of this application provides a slider structure for use on a low-profile anchor trolley pusher, one preferred embodiment of which is, for example Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the device includes a slider 1 body. The slider 1 has two mutually inclined mounting portions 11, which cooperate to form a sliding cavity. The slider 1 is slidably mounted on a slide rail (not shown) through the sliding cavity. Each mounting portion 11 has a mounting groove 13, within which a liner 2 is installed for sliding with the slide rail. When the slider 1 is engaged with the slide rail, the end face of the liner 2 directly contacts the slide rail, further improving the safety of the slider 1 and the slide rail. When the liner 2 is damaged, repairs can be quickly completed by simply removing the liner 2 from the mounting groove 13 and replacing it with a new one.

[0028] Furthermore, such as Figure 3 and Figure 4 As shown, the slider 1 is also provided with a mounting shoulder 12, which has multiple slots 120 for mounting the bracket 4. These slots 120 are arranged sequentially along the length of the mounting shoulder 12 to improve the installation stability of the bracket 4 and the mounting shoulder 12. In addition, the bracket 4 is also equipped with an adjustment mechanism for adjusting the position of the slider 1. When the liner 2 wears or the position of the slider 1 deviates, the relative position of the slider 1 and the bracket 4 can be adjusted through the adjustment mechanism to ensure that the slider 1 can slide stably on the slide rail.

[0029] Understandably, this application sets the slider 1 as an integrated structure. Compared with the traditional split slider 1, the slider 1 in this application has a higher resistance to torsional loads, making the rigidity of the slider 1 far exceed that of the split slider 1. The integrated structure also avoids installing too many fasteners on the slider 1, ensuring that only slots 120 are provided on the mounting parts, so that the overall size of the slider 1 can be designed to be smaller, making it more suitable for installation on low-profile anchor trolleys.

[0030] In addition, to further improve the sliding stability of slider 1, in practical applications, there are two sliders 1. The two sliders 1 are installed on both sides of the slide rail and connected by brackets 4. The relative position between the two brackets 4 remains stable so that the width between the two slide cavities matches the width of the guide rails on both sides, thus preventing slider 1 from detaching from the slide rail.

[0031] In this embodiment, as Figure 2As shown, a limiting groove 130 is provided in the mounting groove 13, and a limiting block 21 that cooperates with the limiting groove 130 is provided on the liner 2. The limiting block 21 and the limiting groove 130 can improve the installation stability of the liner 2, allowing the liner 2 to slide in the mounting groove 13 along a fixed direction. Fixing components for fixing the liner 2 are installed at both ends of the mounting groove 13. When installing the liner 2, after aligning the limiting block 21 with the limiting groove 130, the liner 2 is inserted into the mounting groove 13, allowing the liner 2 to slide in the mounting groove 13 along a fixed direction. The fixing components at both ends serve to seal the liner 2, preventing relative sliding between the liner 2 and the mounting groove 13 during the cooperation with the slide rail.

[0032] Specifically, such as Figure 1 and Figure 2 As shown, the fixing component includes a baffle 3. Mounting holes 14 are provided at both ends of the slider 1. The baffle 3 is fixedly mounted on the slider 1 by bolts 100, and the end of the baffle 3 overlaps with the end of the mounting groove 13 to prevent the liner 2 from detaching from the mounting groove 13. The sealing effect of the baffle 3 can limit the liner 2 to the left and right, while the limiting block 21 and the limiting groove 130 can limit the liner 2 to the up and down. Thus, the liner 2 can be limited in all directions. In addition, it can improve the replacement efficiency of the liner 2. When the liner 2 is damaged, simply loosen the bolts 100 and remove the baffle 3 to release the seal on the liner 2. The user can then simply remove the damaged liner 2 and replace it.

[0033] Furthermore, such as Figure 3 As shown, the liner 2 protrudes from the mounting groove 13. Compared to the mounting part 11, the liner 2 is closer to the slide rail, which can prevent the slider 1 from directly contacting the slide rail. It should be noted that the slider 1 is more expensive and more complicated to replace, while the liner 2 is cheaper and easier to replace. Using only the liner 2 to contact the slide rail can effectively improve the service life of the slider 1 and the slide rail, and reduce the maintenance and repair costs of the slider 1.

[0034] Additionally, in this application, the angle between the two mounting portions 11 on the same slider 1 is 90° to ensure that the angle between the mounting portion 11 and the two guide surfaces of the guide rail is consistent, allowing the liner 2 to fit tightly against the slide rail, improving the sliding stability of the slider 1 and reducing the wear rate of the liner 2. Furthermore, the connection between the two mounting portions 11 is rounded, which effectively reduces stress concentration, improves structural strength, and gives the slider 1 a longer service life.

[0035] It should be noted that the angle between the two mounting parts 11 on the same slider 1 can also be adjusted according to the actual situation, as long as the contact surfaces of the liner 2 and the slider 1 are parallel to each other.

[0036] In this embodiment, the liner 2 comprises a lighter nylon plate. The nylon plate has self-lubricating properties, which can effectively reduce the friction between the liner 2 and the slide rail. In addition, the nylon plate can also absorb the vibration and impact during the movement of the slider 1, preventing damage to the propeller structure. Since the nylon plate is inexpensive, the maintenance and upkeep costs of the slider 1 can be effectively reduced.

[0037] Furthermore, such as Figure 3 As shown, the liner 2 is provided with a cavity 22 that communicates with the outside. The cavity 22 can reduce the material used in the liner 2 and reduce the cost. On the other hand, it can optimize the stress distribution of the liner 2, disperse the pressure between the liner 2 and the slide rail, avoid stress concentration at a certain point of the liner 2 which would cause the liner 2 to break, and thus improve the service life of the liner 2.

[0038] In this embodiment, as Figure 2 and Figure 4 As shown, the slot 120 is elongated. When the installation position of the slider 1 and the bracket 4 needs to be adjusted, the position of the bracket 4 can be finely adjusted along the long side of the slot 120, thereby improving the compatibility between the slider 1 and the bracket 4. The degree of fit between the slider 1 and the slide rail is determined by the distance between the two sliders 1. When it is necessary to change the degree of fit between the slider 1 and the slide rail, the user can adjust the distance between the two sliders 1 through the adjustment mechanism in conjunction with the slot 120 to ensure that the slider 1 can be stably installed on the slide rail.

[0039] Furthermore, such as Figure 4 As shown, the adjustment mechanism includes a set screw 200. The side of the bracket 4 has a screw hole 41 that mates with the set screw 200. The end of the set screw 200 abuts against the side of the slider 1. The relative position of the slider 1 and the bracket 4 can be changed by adjusting the position of the set screw 200. When the liner 2 wears, the distance between the liner 2 and the slide rail changes. At this time, the user only needs to tighten the set screw 200 to push the slider 1 to move along the long side of the slot 120, thereby allowing the liner 2 to move closer to the slide rail, ensuring that the slider 1 can continue to slide stably on the slide rail after adjustment.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
