Description

Technical Field

[0001] This utility model belongs to the technical field of tunneling support equipment, specifically relating to a drilling machine for an integrated tunneling and anchoring machine. Background Technology

[0002] For tunneling operations in deep, thick coal seams prone to rock bursts, it is necessary to conduct drill cuttings testing on the mine roadways. Based on the test data, the level of the rock burst hazard zone is determined, allowing for the establishment of appropriate early warning and response plans. Currently, mine roadway construction typically employs a roadheader-anchor (BAR) system for simultaneous tunneling and support. However, since the BAR's anchoring mechanism lacks the capability to drill relief holes, a supporting drilling rig (commonly pneumatic or crawler-mounted hydraulic drilling rigs) is required. During construction, the BAR and drilling rig need to be repeatedly moved and repositioned within the roadway. This repositioning process consumes significant time and manpower, severely limiting construction efficiency and resulting in high labor intensity. Utility Model Content

[0003] This utility model provides a drilling machine for a tunneling and anchoring integrated machine, which aims to improve the construction efficiency of mines prone to rock bursts and reduce labor intensity.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a drilling machine for an integrated tunneling and anchoring machine, comprising: The base is used to connect to the cutting arm of the tunneling and anchoring machine and is located below the support assembly of the tunneling and anchoring machine. The base is provided with a slide rail extending along the axial direction of the cutting arm. The slide block is slidably connected to the slide rail and connected to the base via the first hydraulic cylinder; The swing seat is hinged to the slide seat at the front end facing the excavation face, and connected to the slide seat at the rear end facing away from the excavation face through a second hydraulic cylinder. The swing seat is driven by the second hydraulic cylinder to swing up and down. The drilling machine body is rotatably connected to the swing base, and a swing angle locking structure is provided between the drilling machine body and the swing base; The first hydraulic cylinder, the second hydraulic cylinder, and the drilling machine body are all driven by the hydraulic system of the integrated tunneling and anchoring machine, and the motion control elements of the three are integrated into the operating table of the integrated tunneling and anchoring machine.

[0005] In one possible implementation, the base is provided with two guide rails as slides along the width of the drilling and anchoring machine, and there is space between the two guide rails suitable for the front end of the drilling machine body to be inserted; the lower surface of the slide is connected to two pressure plates, and the two pressure plates form a sliding groove with the lower surface of the slide, and the openings of the two sliding grooves are opposite to each other or back to back; the two guide rails are respectively slidably embedded in one of the sliding grooves.

[0006] In some embodiments, the front end of the slide is provided with two first connecting ears spaced apart along the width direction, the rear end is provided with two second connecting ears spaced apart along the width direction, and the middle part is provided with two third connecting ears spaced apart along the width direction; wherein, both first connecting ears are hinged to the front end of the slide; the two second connecting ears are respectively connected to the base through a first hydraulic cylinder, and the two first hydraulic cylinders are respectively placed on both sides of the slide; the two third connecting ears are respectively hinged to a second hydraulic cylinder, and both second hydraulic cylinders are hinged to the rear end of the slide.

[0007] For example, a swing arm is provided on each side of the swing base, and a first pin is provided at the front end of each swing arm. The two first pins are respectively hinged to two first connecting ears. A second pin is provided at the rear end of each swing arm. The two second pins are respectively hinged to two second hydraulic cylinders. A slewing bearing is provided between the two swing arms of the swing base, and the drilling machine body is connected to the slewing bearing.

[0008] For example, a first locking plate is provided on the side of the slewing bearing, and a number of locking holes are distributed at intervals along the circumference of the slewing bearing on the first locking plate; a fixed shaft is provided at the bottom of the drilling machine body, and the fixed shaft passes through the slewing bearing; a second locking plate is provided at the bottom of the drilling machine body on the side of the fixed shaft, and a pin passes through the second locking plate, and the pin is inserted into one of the locking holes to form a swing angle locking structure.

[0009] In one possible implementation, the drilling machine body includes: The base is rotatably connected to the swing seat, and the base is provided with a track. The base has a drive cavity that extends through it along its axial direction. A hydraulic drilling mechanism, slidably connected to a track and connected to a hydraulic system; The clamp is connected to the front end of the base and axially aligned with the hydraulic drilling mechanism; The third hydraulic cylinder is located in the drive chamber and its output end is connected to the hydraulic drilling mechanism. The third hydraulic cylinder is connected to the hydraulic system.

[0010] In some embodiments, a push rod is slidably connected inside the drive cavity. One end of the push rod is connected to the hydraulic drilling mechanism, and the other end extends backward out of the drive cavity and is connected to the output end of the third hydraulic cylinder.

[0011] For example, the drilling machine for the tunneling and anchoring machine also includes a pipeline system, which includes water pipelines and oil pipelines. Both the water pipelines and oil pipelines are connected to the operating table along with the drive pipeline of the cutting arm. The operating table is provided with an external water connection for connecting the water pipelines.

[0012] In some embodiments, the drilling machine for the integrated excavator and anchor also includes a folding platform spaced apart in front of the base. The folding platform includes a fixed plate and a movable plate. The fixed plate is connected to the upper surface of the cutting arm, and the movable plate is hinged to the fixed plate. The movable plate has an unfolded state that flips to the front or rear of the fixed plate, and also has a folded-up state that flips to the top of the fixed plate.

[0013] For example, the movable plate has a first tongue plate on its edge away from its hinge axis, and the fixed plate has a second tongue plate and a locking pin on its edge; in the retracted state, the first tongue plate and the second tongue plate are aligned and the locking pin passes through them together.

[0014] The beneficial effects of the drilling machine for the integrated tunneling and anchoring machine provided by this utility model are as follows: Compared with the prior art, the drilling machine for the integrated tunneling and anchoring machine of this utility model has a base fixed on the cutting arm, and the slide seat cooperates with the slide rail on the base to slide back and forth under the drive of the first hydraulic cylinder. The swing seat is hinged to the slide seat and can swing up and down under the drive of the second hydraulic cylinder. This allows the drilling machine body, which is rotatably connected to the swing seat, to obtain the freedom of back and forth movement, up and down movement, and left and right swing. This allows the drill rod of the drilling machine body to be aligned with the target position of the tunneling section to drill the hazard relief and pressure relief hole. This enables the integrated installation of the drilling machine body on the integrated tunneling and anchoring machine, eliminating the need for an additional auxiliary drilling machine. This saves the time of frequently moving and repositioning the integrated tunneling and anchoring machine and the drilling machine during construction, which not only significantly improves the construction efficiency of rockburst mines, but also greatly reduces labor intensity.

[0015] The connection between the swing seat and the slide seat adopts a method in which the front end of the swing seat is hinged and the rear end is driven by the second hydraulic cylinder to swing up and down. This, combined with the elevation angle of the cutting arm, enables the adjustment of the swing angle of the drilling machine body, thereby reducing the height space required for the drilling machine body to swing up and down, avoiding motion interference between the drilling machine body and the support components, and thus meeting the installation requirements of the drilling machine body in the narrow and low space between the cutting arm and the support components.

Detailed Implementation

[0018] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] It should be noted that when an element is referred to as being "set on" or "connected to" another element, it can be directly on or indirectly on the other element. It should be understood that the terms "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and 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 therefore should not be construed as a limitation of this application. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" or "several" means two or more, unless otherwise explicitly specified.

[0020] It should be explained that while extensive innovative research has been conducted both domestically and internationally on integrated roadheader-anchor machines and pressure relief hole drills, no application cases have yet been found integrating pressure relief hole drills into integrated roadheader-anchor machines. The main reason is that the suitable installation location for a pressure relief hole drill is only on the top wall of the cutting arm. However, the cutting arm of an integrated roadheader-anchor machine requires the installation of a dust removal fan and temporary support components. The space between the cutting arm and the temporary support components is very narrow and low, making it difficult to meet the flexible movement space requirements for the pressure relief hole drill to drill at the target location. Therefore, the core of this invention lies in achieving a reasonable arrangement of the drill in a narrow and low space, avoiding motion interference problems.

[0021] Please refer to the following: Figures 1 to 7 The drilling machine for the integrated tunneling and anchoring machine provided by this utility model will now be described. The drilling machine for the integrated tunneling and anchoring machine includes a base 10, a slide 20, a swing seat 40, and a drilling machine body 60. The base 10 is connected to the cutting arm 91 of the integrated tunneling and anchoring machine 90 and is located below the support assembly 92 of the integrated tunneling and anchoring machine 90. The base 10 is provided with a slide rail 100 extending axially along the cutting arm 91. The slide 20 is slidably connected to the slide rail 100 and connected to the base 10 via a first hydraulic cylinder 30. The swing seat 40 faces the front end of the tunneling face. The rear end of the machine, which is hinged to the slide 20 and faces away from the tunneling face, is connected to the slide 20 via the second hydraulic cylinder 50. The swing seat 40 is driven by the second hydraulic cylinder 50 to swing up and down. The drilling machine body 60 is rotatably connected to the swing seat 40 and is provided with a swing angle locking structure between it and the swing seat 40. The first hydraulic cylinder 30, the second hydraulic cylinder 50, and the drilling machine body 60 are all driven by the hydraulic system of the tunneling and anchoring machine 90, and the motion control elements 94 of the three are integrated into the operating table 93 of the tunneling and anchoring machine 90.

[0022] It should be noted that in this embodiment, the base 10 can be fixedly connected to the top surface of the cutting arm 91 by bolts, and the slide rail 100 on the base 10 can be fixed to the base 10 by bolts, or it can be integrally machined onto the base 10; the front end of the swing seat 40 is hinged to the slide 20, and the rear end is connected to the base 10 through the first hydraulic cylinder 30. Since the swing seat 40 is higher than the base 10, the first hydraulic cylinder 30 is arranged in a vertically inclined manner, which not only drives the rear end of the swing seat 40 to swing up and down through extension and retraction, but also does not occupy the space above the swing seat 40 in terms of height, which is conducive to compressing the overall structural height; drilling The drilling machine body 60 and the swing seat 40 can be connected by a slewing bearing 42 to achieve rotational coordination. At the same time, considering the saving of height space, the left and right swing of the drilling machine body 60 relative to the swing seat 40 can be achieved manually (on the one hand, the slewing bearing 42 can ensure smooth and flexible rotation, and on the other hand, only the left and right swing angle needs to be adjusted once for the same tunnel, resulting in a low adjustment frequency). After the left and right swing is manually adjusted to the correct position, the swing angle locking structure is used to lock the left and right swing freedom of the drilling machine body 60 relative to the swing seat 40, thereby ensuring the stability of the drilling machine body 60 at the current drilling angle.

[0023] The drilling machine for the integrated tunneling and anchoring machine provided in this embodiment shares the same hydraulic system with the integrated tunneling and anchoring machine 90. At the same time, the motion control element 94, such as the control valve, used to control the first hydraulic cylinder 30, the second hydraulic cylinder 50 and the drilling machine body 60 to perform actions is integrated on the operating table 93 of the integrated tunneling and anchoring machine 90. This not only saves the space occupied by a separate hydraulic drive module, but also improves the compactness and ease of operation of the whole machine.

[0024] Compared with the prior art, the drilling machine for the integrated tunneling and anchoring machine provided in this embodiment has a base 10 fixed on the cutting arm 91. The slide 20 cooperates with the slide rail 100 on the base 10 and can slide back and forth under the drive of the first hydraulic cylinder 30. The swing seat 40 is hinged to the slide 20 and can swing up and down under the drive of the second hydraulic cylinder 50. This allows the drilling machine body 60, which is rotatably connected to the swing seat 40, to have the freedom of back and forth movement, up and down movement, and left and right swing. This allows the drill rod of the drilling machine body 60 to be aligned with the target position of the tunneling section to drill the hazard relief and pressure relief hole. This enables the integrated installation of the drilling machine body 60 on the integrated tunneling and anchoring machine 90 without the need for an additional drilling machine. This saves the time of frequently moving and repositioning the integrated tunneling and anchoring machine 90 and the drilling machine during construction. This not only significantly improves the construction efficiency of rockburst mines, but also greatly reduces labor intensity.

[0025] The connection between the swing seat 40 and the slide seat 20 is achieved by the swing seat 40 being hinged at the front end and driven by the second hydraulic cylinder 50 to swing up and down. This, combined with the elevation angle of the cutting arm 91, allows for the adjustment of the swing angle of the drilling machine body 60. This reduces the height space required for the drilling machine body 60 to swing up and down, avoids motion interference between the drilling machine body 60 and the support assembly 92, and thus meets the installation requirements of the drilling machine body 60 in the narrow and low space between the cutting arm 91 and the support assembly 92.

[0026] In some embodiments, see Figure 4 and Figure 5 The base 10 is provided with two guide rail plates 11 at intervals along the width direction of the drilling and anchoring machine 90 as slide rails 100, and there is space between the two guide rail plates 11 suitable for the front end of the drilling machine body 60 to be inserted; the lower surface of the slide 20 is connected with two pressure plates 21, and the two pressure plates 21 form a slide groove 211 between the two pressure plates 21 and the lower surface of the slide 20, and the groove openings of the two slide grooves 211 are opposite to each other or back to back; the two guide rails are respectively slidably embedded in one of the slide grooves 211.

[0027] The two guide rail plates 11 can be fixed to the base 10 with bolts, thereby providing the drilling machine body 60 with a space for vertical swinging by utilizing the space between the two guide rail plates 11. This helps to reduce the installation height of the drilling machine body 60 relative to the cutting arm 91, improve the structural compactness of the whole machine in the height direction, and avoid motion interference when the drilling machine body 60 swings up and down in the narrow and low space between the cutting arm 91 and the support assembly 92.

[0028] The pressure plate 21 can adopt an L-shaped structure, which allows the pressure plate 21 to be fixed to the bottom of the slide 20, forming a side-opening groove 211 between the pressure plate 21 and the lower surface of the slide 20. Based on this, the two pressure plates 21 can be arranged opposite each other so that the openings of the two grooves 211 are facing each other or away from each other. The pressure plate 21 and the bottom wall of the slide 20 can be fastened to each other with bolts. During assembly, the guide rail plate 11 can be fixed to the base 10 first, and then the slide 20 can be placed on the two guide rail plates 11. Then, the two pressure plates 21 are installed to constrain the two guide rail plates 11 respectively, so that the slide 20 can slide only along the groove 211.

[0029] The structure in which the slide block 20 is slidably connected to the base 10 by the above-mentioned guide plate 11 and pressure plate 21 has very little requirement for height space, which helps to further improve the overall structure’s compactness in the height direction, thereby meeting the requirement of the drilling machine body 60 to move without interference in the narrow and low space between the cutting arm 91 and the support assembly 92.

[0030] For specific details, please refer to... Figures 1 to 5In this embodiment, the slide 20 has two first connecting ears 22 spaced apart along the width direction at its front end, two second connecting ears 23 spaced apart along the width direction at its rear end, and two third connecting ears 24 spaced apart along the width direction in its middle part. Both first connecting ears 22 are hinged to the front end of the swing seat 40. The two second connecting ears 23 are each connected to the base 10 via a first hydraulic cylinder 30, and the two first hydraulic cylinders 30 are positioned on opposite sides of the swing seat 40. Each of the two third connecting ears 24 is hinged to a second hydraulic cylinder 50, and both second hydraulic cylinders 50 are hinged to the rear end of the swing seat 40.

[0031] The thickness of the swing base 40 can be fully utilized to make the hinge position between the first connecting ear 22 and the front end of the swing base 40 as low as possible, and the hinge position between the second hydraulic cylinder 50 and the rear end of the swing base 40 as high as possible. This ensures that the second hydraulic cylinder 50 can obtain a sufficient tilt angle without being higher than the swing base 40, thus ensuring that the upward component force generated by the second hydraulic cylinder 50 on the rear end of the swing base 40 when it extends is sufficient. This allows the second hydraulic cylinder 50 to output a smaller amount of power to drive the swing base 40 to swing up and down. This not only helps to reduce the cylinder diameter of the second hydraulic cylinder 50, but also allows the length of the second hydraulic cylinder 50 to be shortened by using a larger tilt angle, thereby improving the compactness of the overall structure.

[0032] Here, the distance between the two second connecting ears 23 can be greater than the distance between the two first connecting ears 22, so that at least the front end of the swing seat 40 is located between the two first connecting ears 22. This reduces the installation height of the swing seat 40 relative to the cutting arm 91. On this basis, the two first hydraulic cylinders 30 connected to the second connecting ears 23 are placed on both sides of the swing seat 40, so that the swing seat 40 and the first hydraulic cylinders 30 are basically at the same height, thereby improving the compactness of the overall structure in the height direction.

[0033] One end of the first hydraulic cylinder 30 is connected to the first connecting ear 22 at the front end of the slide block 20, and the other end is connected to the rear end of the base 10. This allows the stroke of the first hydraulic cylinder 30 to be maximized, thereby increasing the forward and backward movement of the slide block 20 in conjunction with the length of the slide rail 100, and avoiding insufficient forward movement of the slide block 20 which would affect the drilling depth.

[0034] For some possible implementations, please refer to [link / reference]. Figure 5 Each side of the swing base 40 is provided with a swing arm 41. The front end of each swing arm 41 is provided with a first pin 411, and the two first pins 411 are respectively hinged to the two first connecting ears 22. The rear end of each swing arm 41 is provided with a second pin 412, and the two second pins 412 are respectively hinged to the two second hydraulic cylinders 50. A rotary bearing 42 is provided between the two swing arms 41 in the swing base 40, and the drilling machine body 60 is connected to the rotary bearing 42.

[0035] The front ends of the two swing arms 41 can be connected as one unit by a crossbeam. The slewing bearing 42 is set on the crossbeam. The outer ring of the slewing bearing 42 is fixed to the crossbeam by bolts, and the inner ring of the slewing bearing 42 is connected to the drilling machine body 60 by bolts or other means, making the overall structure compact.

[0036] As an optional connection structure of the drilling machine body 60 on the swing base 40, please refer to Figure 5 and Figure 6 The swing base 40 is provided with a first locking plate 43 on the side of the rotary bearing 42. The first locking plate 43 has a plurality of locking holes 431 distributed at intervals along the circumference of the rotary bearing 42. The bottom of the drilling machine body 60 is provided with a fixed shaft 611, which passes through the rotary bearing 42. The bottom of the drilling machine body 60 is provided with a second locking plate 613 on the side of the fixed shaft 611. A pin passes through the second locking plate 613 and is inserted into one of the locking holes 431 to form a swing angle locking structure.

[0037] The drilling machine body 60 utilizes its bottom fixed shaft 611 to pass through the movable ring (inner ring) of the rotary bearing 42, thereby achieving a rotatable connection with the swing base 40. The first locking plate 43 and the second locking plate 613 are staggered vertically. When the pin is pulled out, the drilling machine body 60 can swing flexibly left and right based on the rotary bearing 42. After swinging to the correct position, the pin can be reinserted into the locking hole 431 aligned with the current swing angle to lock the swing angle of the drilling machine body 60. The structure is simple and compact, and does not occupy additional height space.

[0038] Figure 6 The diagram shows a specific structure of a drilling machine body 60. The drilling machine body 60 includes a base 61, a hydraulic drilling mechanism 62, a clamp 63, and a third hydraulic cylinder 64. The base 61 is rotatably connected to a swing seat 40, and a track 612 is provided on the base 61. The base 61 has a drive cavity that extends through it along its axial direction. The hydraulic drilling mechanism 62 is slidably connected to the track 612 and connected to the hydraulic system. The clamp 63 is connected to the front end of the base 61 and is axially aligned with the hydraulic drilling mechanism 62. The third hydraulic cylinder 64 is located in the drive cavity and its output end is connected to the hydraulic drilling mechanism 62. The third hydraulic cylinder 64 is connected to the hydraulic system.

[0039] It should be understood that the hydraulic drilling mechanism 62 here can be understood as a drilling mechanism that uses a hydraulic system as a power source. For example, it may include a rotary seat 621 slidably connected to the track 612, a rotating head 622 rotatably connected to the rotary seat 621 for clamping the drill rod, and a hydraulic motor 623 connected to the rotary seat 621 and whose output end is connected to the rotating head 622. The hydraulic system provides power to the hydraulic motor 623, which drives the rotating head 622 to rotate, thereby driving the drill rod to rotate.

[0040] During drilling, the first hydraulic cylinder 30 drives the slide block 20 to slide towards the cutting surface, while the second hydraulic cylinder 50 drives the swing block 40 to adjust the vertical swing angle (the horizontal swing angle remains constant in the current roadway, so it only needs to be manually adjusted before the first drilling after changing roadways). This aligns the drill rod installed on the hydraulic drilling mechanism 62 with the target point. Then, the hydraulic drilling mechanism 62 is started (the hydraulic motor 623 starts, and the drill rod rotates). The third hydraulic cylinder 64 drives the hydraulic drilling mechanism 62 to advance the drill rod forward. Considering the stability of the drill rod, the clamp 63 at the front end of the seat 61 is used to clamp and constrain the drill rod. After drilling is completed, the third hydraulic cylinder 64 drives the hydraulic drilling mechanism 62 to move backward and gradually pull out the drill rod. During this process, the clamp 63 also constrains the drill rod to prevent bending and deformation due to its large length.

[0041] To further save space, such as Figure 6 As shown, in this embodiment, a push rod 65 is slidably connected inside the drive cavity. One end of the push rod 65 is connected to the hydraulic drilling mechanism 62, and the other end extends backward out of the drive cavity and is connected to the output end of the third hydraulic cylinder 64.

[0042] The base 61 can be a long cylindrical component to form a space inside as a drive chamber. The push rod 65 and the third hydraulic cylinder 64 are placed inside the drive chamber, which avoids the push rod 65 and the third hydraulic cylinder 64 occupying additional space and improves the compactness of the overall structure. The sliding fit between the push rod 65 and the drive chamber guides the cylinder rod of the third hydraulic cylinder 64, thereby preventing the cylinder rod of the third hydraulic cylinder 64 from bending under stress due to excessive extension length during drilling operations.

[0043] It should be noted that you should refer to [link / reference]. Figure 1 and Figure 2 The drilling machine for the tunneling and anchoring machine also includes a pipeline system 70, which includes water pipelines and oil pipelines. Both the water pipelines and oil pipelines are connected to the operating table 93 along with the drive pipeline of the cutting arm 91. The operating table 93 is provided with an external water channel 71 for connecting the water pipelines.

[0044] The movement of the cutting arm 91 is based on the high-pressure hydraulic oil supplied to its drive cylinders by the hydraulic system through the drive pipeline. Without changing the drive pipeline of the cutting arm 91, it is only necessary to add water pipelines and oil pipelines along its arrangement path to achieve the oil supply to the first hydraulic cylinder 30 and the second hydraulic cylinder 50, as well as the oil and water supply to the drilling machine body 60 (which adopts a wet rotary mechanism). The pipeline arrangement is simple and neat.

[0045] It should be explained that after the water pipeline extends to the control panel 93, it can obtain water by connecting to the external water pipeline 71. The oil pipeline is connected to the motion control element 94, such as the hydraulic valve group, installed on the control panel 93. The hydraulic valve group is connected to the hydraulic pump station through another pipeline to obtain high-pressure hydraulic oil.

[0046] For some possible implementations, please refer to [link / reference]. Figure 1 , Figure 2 and Figure 7 The drilling machine for the integrated excavation and anchoring machine also includes a folding platform 80 spaced apart in front of the base 10. The folding platform 80 includes a fixed plate 81 and a movable plate 82. The fixed plate 81 is connected to the upper surface of the cutting arm 91, and the movable plate 82 is hinged to the fixed plate 81. The movable plate 82 has an unfolded state that flips to the front or rear of the fixed plate 81, and also has a folded state that flips to the top of the fixed plate 81.

[0047] The folding platform 80 provides a platform for workers to step on during drilling operations, improving operational convenience. It also allows the movable plate 82 to be folded over and stored on top of the fixed plate 81, reducing space occupation and avoiding interference with the normal operation of the drilling machine body 60.

[0048] For details, see Figure 7 The movable plate 82 is provided with a first tongue plate 821 at the edge away from its hinge axis, and the fixed plate 81 is provided with a second tongue plate 811 and a locking pin 812 at the edge. In the storage state, the first tongue plate 821 and the second tongue plate 811 are aligned and the locking pin 812 is inserted through them together.

[0049] To prevent it from falling or being lost, the locking pin 812 can be connected to the fixed plate 81 via a chain. After the movable plate 82 is folded onto the fixed plate 81, the first tongue plate 821 and the second tongue plate 811 are inserted together by the locking pin 812. This can prevent the movable plate 82 from being freely flipped open by the vibration of the machine body during the construction operation, thereby improving the stability of the storage state.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
