Description

Technical Field

[0001] The utility model belongs to the technical field of cab seat installation for anchor bolt construction vehicles, in particular to a double-station driver seat installation structure for an anchor bolt trolley. Background Art

[0002] In the construction of mines, underground tunnels, culverts and road slopes, spray anchoring operations are usually required to reinforce geological structures. Traditional spray anchoring operations require manual drilling, anchor insertion and pouring of slurry. With the advancement of technology, spray anchoring operations have gradually been replaced by anchor trolleys. For example, the patent with application number CN201811591268.1 discloses a hydraulic anchor trolley that can replace manual work to quickly complete the drilling, anchor insertion and other tasks of spray anchoring operations. The chassis driving operating system and the spray anchor operating system of this type of trolley are usually set on two independent operating tables in the cab, and as Figure 1 As shown, the two operating consoles share the same driving seat, so the existing driving seat can usually adapt to the two operating consoles by adjusting the angle of the seat and adjusting the distance between the seat and the operating console.

[0003] To accommodate the limited working space within mines, tunnels, and culverts, the cabs of anchor bolters are typically compactly designed, resulting in limited interior space. For ease of operation, the anchor bolter's travel system console is typically located on one side of the cab, while the seat is typically positioned on the opposite side, as close to the cab's interior wall as possible. The spray anchor system console is located in the center of the front end of the cab. Consequently, when the seat shifts from the travel system console to the spray anchor system console, it's not centered between the two cab sides, but rather toward the side of the cab where the seat is mounted. This causes a misalignment between the seat and the spray anchor system console along the cab's width, compromising the operator's sitting comfort. Utility Model Content

[0004] In order to solve the shortcomings of the existing technology, the utility model provides a double-position driving seat installation structure for an anchor trolley. When the seat is rotated toward the anchor spraying operating table, the seat is synchronously adjusted to the middle position in the width direction of the cab, so that the operator can obtain a more comfortable operating sitting posture, and the adjustment method is simple and quick.

[0005] In order to achieve the purpose of this utility model, the following scheme is proposed:

[0006] A double-station driving seat installation structure for an anchor trolley is provided, wherein a driving operating platform is provided on one side of the rear end of the cab, a seat is provided on the other side of the rear end of the cab, and a spray anchor operating platform is provided in the middle of the front end of the cab.

[0007] A support plate is provided at the bottom of the seat, a support rod is vertically provided at the bottom of the support plate; two layers of mutually spaced discs are coaxially provided at the lower end of the support rod, and a gear is coaxially provided at the support rod.

[0008] A strip hole is provided on the bottom plate of the cab corresponding to the bottom of the seat. The length direction of the strip hole is parallel to the direction of the connecting line between the driving operating platform and the seat. A rack is provided on the bottom plate, which is located on the side of the strip hole close to the spray anchor operating platform, and the teeth of the rack are facing the other side of the strip hole.

[0009] The lower end of the support rod passes through the strip hole, the two discs are in sliding contact with the upper and lower surfaces of the bottom plate respectively, and the gear is meshed with the rack.

[0010] The support rod is arranged to move along the length direction of the strip hole; when the seat faces the driving operating table, the support rod is located at one end of the strip hole close to the side of the cab; when the seat faces the spray anchor operating table, the support rod is located at the other end of the strip hole and in the middle position in the width direction of the cab.

[0011] The beneficial effect of the present invention is that the present invention can not only adjust the orientation of the seat, but also synchronously adjust the relative position of the seat and the spray anchor operating table in the width direction of the cab, so that the seat can be aligned with the corresponding operating table regardless of whether it is facing the driving operating table or the spray anchor operating table, thereby providing the operator with a more comfortable sitting posture.

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] like Figure 1 As shown, a double-station driving seat installation structure for an anchor trolley is provided, wherein a driving operating platform 11 is provided on one side of the rear end of the cab, a seat 2 is provided on the other side of the rear end of the cab, and a spray anchor operating platform 12 is provided in the middle of the front end of the cab.

[0020] Specifically, such as Figure 2 、 Figure 3 As shown, a support plate 21 is provided at the bottom of the seat 2, and a support rod 22 is vertically provided at the bottom of the support plate 21. The support rod 22 is used to control the height of the seat 2. Specifically, the support rod 22 can be hydraulically controlled or driven by a linear motor; the lower end of the support rod 22 is coaxially provided with two layers of mutually spaced discs 221, and the support rod 22 is coaxially provided with a gear 23.

[0021] Specifically, such as Figure 1 、 Figure 2 As shown, a strip hole 131 is provided on the bottom plate 13 of the cab corresponding to the bottom of the seat 2. The length direction of the strip hole 131 is parallel to the direction of the line connecting the driving operating platform 11 and the seat 2. The bottom plate 13 is provided with a rack 14, which is located on the side of the strip hole 131 close to the spray anchor operating platform 12, and the teeth of the rack 14 are facing the other side of the strip hole 131.

[0022] Specifically, such as Figure 2 、 Figure 3 As shown, the lower end of the support rod 22 passes through the strip hole 131, and the two discs 221 are in sliding contact with the upper and lower surfaces of the base plate 13 respectively to ensure that the support rod 22 is perpendicular to the base plate 13, and to provide a stable sliding connection structure between the support rod 22 and the base plate 13 to prevent the support rod 22 from tipping over, and the gear 23 is engaged with the rack 14.

[0023] The support rod 22 is arranged to move along the length direction of the strip hole 131. In this way, the support rod 22 can be rotated by utilizing the structure in which the gear 23 and the rack 14 are engaged while moving the support rod 22, so as to adjust the angle of the seat 2 synchronously, and the adjustment method is more convenient. Figure 1 As shown, when the seat 2 faces the driving operating platform 11, the support rod 22 is located at one end of the strip hole 131 close to the side of the cab to ensure that there is enough operating space between the seat 2 and the driving operating platform 11. Figure 4As shown, when the seat 2 faces the spray anchor operating platform 12, the support rod 22 is located at the other end of the strip hole 131 and in the middle position in the width direction of the cab. The orientation of the seat 2 refers to the direction of the operator's front after the operator sits on the seat 2.

[0024] This solution can not only adjust the orientation of the seat 2, but also synchronously adjust the relative position of the seat 2 and the spray anchor operating platform 12 in the width direction of the cab, so that the seat 2 can be aligned with the corresponding operating platform regardless of whether it is facing the driving operating platform 11 or the spray anchor operating platform 12, thereby providing the operator with a more comfortable sitting posture.

[0025] Preferably, a slide rail is provided between the seat 2 and the support plate 21, and the sliding direction of the slide rail is consistent with the orientation of the seat 2. The seat 2 is moved relative to the support plate 21 along the sliding direction of the slide rail to adjust the distance between the seat 2 and the operating table to accommodate operators of different heights.

[0026] Preferably, the support rod 22 is a multi-stage telescopic structure, such as a two-stage hydraulic telescopic rod or a three-stage hydraulic telescopic rod, for adjusting the height of the seat 2.

[0027] Preferably, Figure 2 、 Figure 3 As shown, two discs 221 are provided with coaxial annular grooves 222 on opposite sides thereof, and an arc-shaped plate 24 is provided between the two discs 221. The top and bottom edges of the arc-shaped plate 24 are respectively slidably provided in the corresponding annular grooves 222. The arc-shaped plate 24 is provided at the end of a movable rod of a telescopic device 3. The movable rod is parallel to the length direction of the strip hole 131. The housing of the telescopic device 3 is fixed to the side wall of the cab. In this way, the support rod 22 can be pushed to move in the strip hole 131 by the telescopic device 3. Because there is a meshing structure between the gear 23 and the rack 14, the support rod 22 will also rotate during the movement. The above design can simultaneously meet the requirements of the movement and rotation of the support rod 22. The telescopic device 3 is a hydraulic cylinder or a pneumatic cylinder. The control button of the telescopic device 3 is provided on the seat 2, and can also be provided on the driving operating console 11 or the spray anchor operating console 12.

[0028] More preferably, Figure 2 As shown, the rack 14 is arranged below the base plate 13, and the gear 23 is coaxially arranged at the lower end of the support rod 22, so that the meshing structure of the gear 23 and the rack 14 is hidden below the base plate 13 to play a protective role.

[0029] Preferably, Figure 2As shown, reinforcing ribs 15 are provided on both sides of the corresponding strip holes 131 on the top and bottom surfaces of the bottom plate 13. The reinforcing ribs 15 are located between the two discs 221. The two discs 221 are in sliding contact with the corresponding reinforcing ribs 15 respectively. This structure not only improves the structural strength of the bottom plate 13, but also ensures the stability of the connection structure between the support rod 22 and the bottom plate 13.

[0030] The above description is only a preferred embodiment of the present invention and does not represent the only embodiment or limit the present invention. It should be understood by those skilled in the art that various changes or equivalent replacements made to the present invention without departing from the scope of the present invention are within the scope of protection of the present invention.
