Description

Technical Field

[0001] This utility model relates to the field of laser leveling machine technology, and in particular to an adjustment mechanism for the telescopic arm of a laser leveling machine. Background Technology

[0002] Laser screed machines include a telescopic arm structure. The free end of the telescopic arm structure is equipped with a scraper head for leveling the floor. The extension and retraction of the telescopic arm structure drives the scraper head, thereby achieving the floor leveling function. Existing telescopic arm structures include an outer rod and an inner rod movably disposed within the outer rod. A drive mechanism drives the inner rod to slide within the outer rod, which in turn drives the scraper head, thus achieving the floor leveling function.

[0003] Because the inner and outer rods slide in direct contact during sliding, the service life of the telescopic boom structure is greatly shortened, and consequently, the stability of the telescopic boom structure will be greatly reduced under long-term use. Utility Model Content

[0004] The purpose of this invention is to provide an adjustment mechanism for the telescopic arm of a laser leveling machine, which can improve the stability of the telescopic arm during use.

[0005] To achieve the above objectives, this utility model provides an adjustment mechanism for the telescopic arm of a laser leveling machine, including a fixed bracket and an auxiliary device;

[0006] The auxiliary device includes a lower guide rail, a lower slider, an upper guide rail, an upper slider, a slide plate, an actuator arm, a connecting seat, ear plates, a drive assembly, and a stabilizing assembly. The lower guide rail is detachably connected to the fixed bracket and is symmetrically arranged on the lower side of the fixed bracket. The lower slider can slide linearly on the lower guide rail. The upper guide rail is detachably connected to the fixed bracket and is symmetrically arranged on the upper side of the fixed bracket, and is provided with an upper slider that can slide linearly. The slide plate is detachably connected to the lower slider. The actuator arm is installed at the bottom of the slide plate. The connecting seat is integrally formed with the slide plate and connected to the drive assembly. The ear plates are detachably connected to the upper slider and the connecting seat respectively. The stabilizing assembly is located at the bottom of the fixed bracket and is slidably connected to the actuator arm.

[0007] The drive assembly includes a positioning plate and a hydraulic cylinder. The positioning plate is welded to the fixed bracket. The hydraulic cylinder is mounted on the positioning plate, and its output end is connected and fixed to the connecting seat.

[0008] The stabilizing component includes a stabilizing base and a mating member. The stabilizing base is detachably connected to the fixed bracket and is located at the bottom of the fixed bracket. The mating member is disposed on the side of the stabilizing base near the moving arm.

[0009] The mating components include a support platform and a semi-circular guide rail. The support platform is detachably connected to the stabilizer and is located between the stabilizer and the actuator arm. The semi-circular guide rail is integrally formed with the support platform and slides in cooperation with the semi-circular groove at the bottom of the actuator arm.

[0010] The adjustment mechanism for the telescopic arm of the laser leveling machine also includes a protective device, which includes a protective cover and a connecting plate. The protective cover is slidably connected to the fixed bracket and is located on top of the fixed bracket. The connecting plate is welded to the protective cover and is symmetrically arranged, and is detachably connected to the fixed bracket.

[0011] This utility model discloses an adjustment mechanism for a telescopic arm of a laser leveling machine. By setting a lower guide rail and a lower slider, and an upper guide rail and an upper slider, a linear guiding structure can be formed. After the drive component is activated, the cooperation of the sliding plate and the connecting seat facilitates the extension and retraction of the telescopic arm, improving its stability. Moreover, the telescopic arm will not contact the fixed support during sliding. The lower guide rail and lower slider, and the upper guide rail and upper slider can be set as an integral assembly structure, which facilitates overall installation and disassembly for easy maintenance. Compared with the traditional inner and outer rod sliding structure, the structure of this application greatly reduces direct contact by ensuring that the fixed support and the telescopic arm do not contact each other during relatively stable sliding, which helps to better ensure the stability of the telescopic arm structure. Furthermore, the corresponding components can be replaced individually, reducing the cost of use and thus improving the stability of the telescopic arm. Attached Figure Description

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] Example 1:

[0020] like Figures 1 to 3 As shown, where Figure 1 This is a schematic diagram of the overall structure of the adjustment mechanism for the telescopic arm of a laser leveling machine. Figure 2 This is a diagram showing the installation location of the skateboard 106. Figure 3 This is a bottom view of the telescopic arm 107. This utility model provides an adjustment mechanism for a telescopic arm of a laser leveling machine: it includes a fixed bracket 101 and auxiliary devices. The auxiliary devices include a lower guide rail 102, a lower slider 103, an upper guide rail 104, an upper slider 105, a sliding plate 106, the telescopic arm 107, a connecting seat 108, an ear plate 109, a drive assembly, and a stabilizing assembly. The drive assembly includes a positioning plate 110 and a hydraulic cylinder 111. The stabilizing assembly includes a stabilizing seat 112 and a mating component. The mating component includes a support platform 113 and a semi-circular guide rail 114. The aforementioned solution improves the stability of the telescopic arm during use. It is understood that the aforementioned solution improves the stability of the telescopic arm during use and facilitates convenient installation.

[0021] In this embodiment, the fixed bracket 101 can be installed on the body of the leveling machine by bolts. The fixed bracket 101 is provided with a long rectangular cavity through which the connecting seat 108 passes. The fixed bracket 101 is provided with a hanging column. The bottom of the hanging column is a rolling ball. The ball abuts against the top end face of the action arm 107. The hanging column has a T-shaped structure, and the top disc is fixed by bolts.

[0022] The lower guide rail 102 is detachably connected to the fixed bracket 101 and symmetrically arranged on the lower side of the fixed bracket 101. The lower slider 103 can slide linearly on the lower guide rail 102. The upper guide rail 104 is detachably connected to the fixed bracket 101 and symmetrically arranged on the upper side of the fixed bracket 101, and is provided with an upper slider 105 that can slide linearly. The slide plate 106 is detachably connected to the lower slider 103. The actuator arm 107 is installed at the bottom of the slide plate 106. The connecting seat 108 is integrally formed with the slide plate 106 and connected to the drive assembly. The ear plate 109 is detachably connected to the upper slider 105 and the connecting seat 108 respectively. The stabilizing assembly is arranged at the bottom of the fixed bracket 101 and slidably connected to the actuator arm 107. The lower guide rail 102 is a linear rail, fixed by countersunk bolts. The lower slider 103 can slide linearly on the lower guide rail 102. Its internal structure is a common circulating ball structure in the prior art. The upper guide rail 104 is a linear rail, fixed by countersunk bolts. The upper slider 105 can slide linearly on the upper guide rail 104. Its internal structure is a common circulating ball structure in the prior art. The slide plate 106 is connected to the lower slider 103 by bolts and the connecting seat 108 is vertically integrated. The connecting seat 108 cooperates with the drive assembly. The ear plate 109 is connected to the upper slider 105 and the connecting seat 108 by bolts. The stabilizing assembly is used to further improve the stability of the actuator arm 107. The actuator arm 107 is connected to the slide plate 106 by multiple countersunk bolts. A flattening head can be connected and installed on the actuator arm 107.

[0023] Secondly, the positioning plate 110 is welded to the fixed bracket 101; the hydraulic cylinder 111 is mounted on the positioning plate 110, and its output end is connected and fixed to the connecting seat 108. The hydraulic cylinder 111 is fixed to the positioning plate 110 by bolts, and its output end is provided with a stepped external thread post. The external thread post passes through the through hole on the connecting seat 108 and is locked by two locking screws to achieve the connection.

[0024] Then, the stabilizer 112 is detached from the fixed bracket 101 and located at the bottom of the fixed bracket 101; the mating component is disposed on the side of the stabilizer 112 near the actuator arm 107. The stabilizer 112 is tightened and fixed by bolts arranged from bottom to top, and the mating component is used to add a sliding support structure at the bottom to improve stability when the actuator arm 107 moves.

[0025] Finally, the support platform 113 is detached from the stabilizer 112 and located between the stabilizer 112 and the actuator arm 107; the semi-circular guide rail 114 is integrally formed with the support platform 113 and slides in engagement with the semi-circular groove at the bottom of the actuator arm 107. The support platform 113 is fixed by bolts arranged from bottom to top, and the semi-circular guide rail 114 is symmetrically arranged on the top of the support platform 113, with the semi-circular guide rail 114 sliding in engagement with the semi-circular groove at the bottom of the actuator arm 107.

[0026] When using this utility model to improve the stability of the telescopic boom, firstly, by setting the structure of the lower guide rail 102 and the lower slider 103, and the upper guide rail 104 and the upper slider 105, a double linear guide structure can be formed, which is beneficial to improving the movement stability of the boom 107. Furthermore, the boom 107 does not slide into contact with the fixed bracket 101 during movement, allowing for the replacement of a single boom 107, which is less costly than replacing the larger fixed bracket 101 simultaneously. After the hydraulic cylinder 111 extends, the boom 107 extends smoothly with the cooperation of the sliding plate 106 and the connecting seat 108. The device enables the flattened head to move, and the actuator arm 107 will not contact the fixed bracket 101 during sliding. The lower guide rail 102 and lower slider 103, and the upper guide rail 104 and upper slider 105 can be respectively set as an integral assembly structure, which facilitates overall installation and disassembly for easy maintenance. Compared with the traditional inner rod and outer rod sliding structure, the structure of this application greatly reduces the direct contact area after the fixed bracket 101 and the actuator arm 107 do not contact each other during relatively stable sliding, which helps to better ensure the stability of the telescopic arm structure. Moreover, the corresponding components can be replaced individually to reduce the cost of use, thereby improving the stability of the telescopic arm.

[0027] Example 2:

[0028] like Figure 4 As shown, where Figure 4 This is a schematic diagram of the overall structure of the adjustment mechanism for the telescopic arm of a laser screed. Based on the first embodiment, this utility model provides an adjustment mechanism for the telescopic arm of a laser screed. The adjustment mechanism for the telescopic arm of a laser screed also includes a protective device, which includes a protective cover 201 and a connecting plate 202.

[0029] The protective cover 201 is slidably connected to the fixed bracket 101 and is located on top of the fixed bracket 101. The connecting plate 202 is welded to the protective cover 201 and is symmetrically arranged, and is detachably connected to the fixed bracket 101. The fixed bracket 101 is provided with a non-penetrating groove to facilitate the sliding installation of the protective cover 201. The connecting plate 202 is symmetrically welded to the protective cover 201 and is fixed by bolts.

[0030] In this embodiment, by setting the protective cover 201 and the connecting plate 202, a detachable protective structure can be formed on the top of the fixed bracket 101, which is beneficial for protecting the hydraulic cylinder 111 during operation and improving safety.
