Abstract

A seat frame that can be adjusted up and down, including a base, a frame, two movable rods and two fixed rods, the frame is supported on the base by two movable rods and two fixed rods, and the bottoms of the two movable rods are hinged on the base The two movable rods and the two fixed rods are close to the two ends of the base respectively; The barrel adjustment frame moves up and down; a traction device is installed on the base. The overall structure is simple. Compared with the traditional seat frame, the two fixed rods are set as threaded rods, and the adjustable handles are set on the threaded rods, so that the height of the support seat can be easily adjusted. Since the winch is set on the base, so When the seat frame is moving, the seat frame has high mobility, and the hoop is used as the connecting part, which is convenient for installation and disassembly, and enhances the interchangeability.

Description

An adjustable stand

technical field

The utility model relates to the field of racks, in particular to a liftable and adjustable seat rack.

Background technique

In the process of traditional coal mine underground operations, various engineering holes need to be drilled, and the hydraulic motors and drill pipes used for drilling need to be installed on the seat frame, and it is often necessary to adjust the position of the seat frame when drilling holes in different positions. Height and inclination direction, but the current commonly used mounts in production are not very convenient to use when adjusting the height and inclination angle, especially when working in places with relatively narrow spaces, and the mounts need to be adapted to use in various occasions, so It needs to be moved frequently, and the currently commonly used mounts lack certain mobility in terms of movement, and the weight of the mounts is relatively heavy. It is inevitable to consume a lot of labor and lack of automation during the moving process. Therefore, in order to reduce the burden on the operator, a A seat frame that is easy to lift and adjust to meet the needs of the operation process.

Utility model content

Aiming at the deficiencies of the prior art, the utility model proposes a seat frame that is convenient for lifting and adjusting, and the specific technical scheme is as follows:

A seat frame that can be lifted and adjusted is characterized in that it includes a base (1), a frame (4), two movable rods (2) and two fixed rods (3), and the frame (4) is composed of The two movable rods (2) and the two fixed rods (3) are supported on the base (1), the bottoms of the two movable rods (2) are hinged on the base (1), and the two A movable rod (2) and two fixed rods (3) are respectively close to the two ends of the base (1); the two fixed rods (3) are threaded rods, and on the two fixed rods (3) respectively There are lifting sleeves (5) threadedly matched with the fixed rod (3), the two lifting sleeves (5) adjust the frame (4) to move up and down; Traction device (6).

The utility model is realized in this way, the frame (4) moves up and down through the lifting sleeve (5), the frame (4) drives the two movable rods (3) to rotate, and the height and inclination angle of the frame (4) can be adjusted , and the traction device (6) arranged on the base (1) can facilitate the movement of the seat frame.

For realizing the utility model better, can further be:

The two movable rods (2) and the two fixed rods (3) are respectively provided with hoops (7), between the hoops (7) on the two movable rods (2) a first A crossbeam (8), a second crossbeam (9) is arranged between the hoops (7) on the two fixed rods (3), and the frame (4) is respectively installed on the first beam (8) and the second beam (9). Using the hoop, it is easy to assemble, easy to disassemble, evenly stressed, and simple in process.

The lifting sleeve (5) is radially provided with a corresponding handle, and the lifting sleeve (5) is located below the hoop (7). The adjustment handle is easy to manufacture and convenient to force.

The traction device (6) is a winch. Since the winch is a standard part, the cost is low and the interchangeability is strong.

The beneficial effects of the utility model are: the overall structure is simple, compared with the traditional seat frame, the two fixed rods are set as threaded rods, and the lifting sleeves that are threaded with the fixed rods are arranged on the threaded rods, so that the frame can be easily adjusted Due to the winch is set on the base, the mobility of the seat frame is high when it is moving, and the hoop is used as the connecting part, which is convenient for installation and disassembly, and enhances the interchangeability, making the utility model The application adaptability is stronger and the application range is wider.

Detailed ways

The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

As shown in Figures 1 and 2: a liftable and adjustable seat frame includes a base 1, a frame 4, two movable rods 2 and two fixed rods 3, and two movable rods 2 and two fixed rods 3 Hoops 7 are respectively arranged on the top, and a first crossbeam 8 and a second crossbeam 9 are respectively arranged between the hoops 7 of the two movable rods 2 and between the two fixed rods 3, and the frame 4 passes through the support respectively. Set on the first beam 8 and the second beam 9 . The bottoms of the two movable rods 2 are hinged on the base 1, and the two movable rods 2 and the two fixed rods 3 are respectively close to the two ends of the base 1; There is a lifting sleeve 5 threadedly matched with the fixed rod 3, and the lifting sleeve 5 is radially provided with a handle correspondingly, and the lifting sleeve 5 is located below the hoop 7. By rotating the lifting sleeve 5, the frame 4 moves up and down along the two fixed rods 3, and the frame 4 drives the two movable rods 2 to rotate. The winch 6 arranged on the base 1 drives the base 1 to move.
