Description
Technical Field
[0001] This utility model relates to the field of standard pendulum instrument technology, and in particular to a swing seat for an impact-type standard pendulum instrument. Background Technology
[0002] The impact-type standard pendulum vibratory meter is an instrument used in laboratories of departments such as highway construction, building construction, and geological and metallurgical research for material screening and analysis. It includes a base, on which a screen support is vibrating. The screen support has three sliding sleeves, two of which form the inlet and outlet of the aggregate screen. Screen clamping discs are slidably mounted on the three sleeves, and positioning devices are installed on the screen clamping discs. The aggregate screen consists of multiple screen discs, a bottom cover, and a top cover. The screen discs are stacked in order of decreasing screen size from top to bottom. The bottom covers are stacked below all the aggregate screens, and the top covers are stacked above. When the impact-type standard pendulum vibratory meter is working, the screen discs are first stacked as needed to form the aggregate screen. Then, the screen is placed on the screen support through the inlet and outlet formed by the sliding sleeves. The material is placed in the topmost screen disc. The sliding screen clamping discs, through the positioning devices, clamp the aggregate screen to the screen support. Then, the screen support is driven to vibrate, completing the material screening.
[0003] In the existing technology, the impact-type standard pendulum meter has the following problems:
[0004] (1) When screening materials, the impact-type standard vibrating pendulum instrument will drive the screen support (which is the swing seat of this utility model) to vibrate. After long-term use, the positioning device of the screen clamping plate is prone to loosening, causing the aggregate screen to fall off, the screen clamping plates to separate from each other, and the material to spill, which reduces the success rate of the test.
[0005] (2) When screening materials, the impact-type standard vibrating pendulum instrument will generate large vibrations, which will cause it to move on the ground and its stability is insufficient.
[0006] To address this, a swing seat for a shock-type standard pendulum instrument is proposed, which has the advantages of preventing the screen plate from loosening and preventing displacement, thereby solving the problems mentioned in the background technology. Utility Model Content
[0007] The purpose of this invention is to address the shortcomings of existing technologies by proposing a swing seat for a shock-type standard pendulum instrument.
[0008] To achieve the above objectives, this utility model adopts the following technical solution: a swing base for a shock-type standard pendulum instrument, comprising a standard pendulum instrument body, a screen support fixed to the upper part of the standard pendulum instrument body, and side rods welded to the left and right sides of the screen support, a left positioning frame rotatably connected to the left side rod of the screen support, and a right positioning frame rotatably connected to the right side rod of the screen support, with connecting sleeves welded to the opposite ends of the left and right positioning frames, and the connecting sleeves sleeved with the side rods, the left positioning frame being located away from... A plum blossom knob is inserted at one end of the side rod. A threaded hole is opened at the end of the right positioning frame away from the side rod. Several rubber sleeves are glued to the concave surface of the left and right positioning frames, and a spring is embedded in the inner side of each rubber sleeve. Several threaded posts are welded to the bottom of the standard pendulum instrument body, and a reinforcing base is attached to the bottom surface of the standard pendulum instrument body. Several threaded posts penetrate and extend into the inner side of the reinforcing base, and a nut is screwed onto the part of each threaded post extending into the inner side of the reinforcing base.
[0009] As a further description of the above technical solution: each of the four corners of the top surface of the reinforcing base is provided with a clearance opening, and multiple support shells are welded to the top surface of the reinforcing base corresponding to the clearance opening. An electric push rod is fixedly installed inside each support shell, and the bottom of the electric push rod is fixedly connected to an L-shaped steel piece extending to the inside of the clearance opening. The bottom of the L-shaped steel piece is provided with a beveled surface.
[0010] As a further description of the above technical solution: both the left positioning frame and the right positioning frame are provided with arc plates, and the left positioning frame and the right positioning frame are combined to form a semi-ring structure.
[0011] As a further description of the above technical solution: one end of the rubber sleeve has a mounting hole corresponding to the spring.
[0012] As a further description of the above technical solution: the surface of the side rod is provided with an annular groove corresponding to the connecting sleeve, and the connecting sleeve and the side rod are rotatably connected.
[0013] As a further description of the above technical solution: the reinforcing base is a rectangular frame structure, and the top surface of the reinforcing base has several through holes corresponding to the threaded post.
[0014] As a further description of the above technical solution: the bottom of the reinforcing base has a rectangular opening corresponding to the clearance opening, and the size of the rectangular opening is adapted to the size of the L-shaped steel part.
[0015] This utility model has the following beneficial effects:
[0016] In this invention, a left positioning frame and a right positioning frame are rotatably installed on the left and right sides of the screen support of the standard vibrating pendulum instrument body. By pulling the left and right positioning frames in opposite directions, the connecting sleeves of the left and right positioning frames are made to rotate relative to the side rods on both sides of the screen support, so that the left and right positioning frames are combined to form a semi-ring structure. Several rubber sleeves set on the concave surface of the left and right positioning frames are respectively in contact with the side of the screen clamping plate placed on the screen support. Then, the plum blossom knob of the left positioning frame is rotated to screw it into the threaded hole of the right positioning frame until the rubber sleeve and its built-in spring are elastically connected to the screen clamping plate. While satisfying the positioning, it is easy to clamp the screen plate for vibrating screening, avoids the screen plate from loosening, and has the advantage of quick assembly and disassembly.
[0017] In this invention, by placing the reinforcing base at the bottom of the standard pendulum instrument body, several threaded posts on the bottom surface of the standard pendulum instrument body pass through several through holes corresponding to those on the surface of the reinforcing base. Then, nuts are used to fix the threaded posts passing through the through holes. When it is necessary to reinforce the standard pendulum instrument body, the electric push rod built into the support shell is activated, causing the electric push rod to push the L-shaped steel piece down, so that the L-shaped steel piece can pass through the clearance opening of the reinforcing base and be inserted into the ground. Compared with the existing invention, this greatly increases the stability of the standard pendulum instrument body and avoids the phenomenon of displacement of the standard pendulum instrument body due to vibration during use.

In order to facilitate the fixing of the left positioning frame 3 and the right positioning frame 4, a support bar is vertically welded to the end of the left positioning frame 3 and the right positioning frame 4 away from the side rod 7. The support bar of the left positioning frame 3 is interspersed with a plum blossom knob 5, and the support bar of the right positioning frame 4 has a threaded hole 6. The parts not involved in this device are the same as the existing technology or can be implemented by the existing technology. The principle of the standard pendulum instrument is the existing known technology, and there are mature products. Therefore, its principle will not be further explained.
[0026] In one embodiment, the four corners of the top surface of the reinforcing base 9 are provided with clearance openings 14, and multiple support shells 12 are welded to the top surface of the reinforcing base 9 corresponding to the clearance openings 14. An electric push rod 13 is fixedly installed inside each support shell 12, and the bottom of the electric push rod 13 is fixedly connected to an L-shaped steel piece 15 extending to the inside of the clearance opening 14. The bottom of the L-shaped steel piece 15 is provided with a beveled surface.
