Description

A jacking device for eccentric assembly of vibrating conveyor

technical field

The utility model belongs to the technical field of silk-making equipment tools, in particular to a jacking device for an eccentric assembly of a vibrating conveyor.

Background technique

The vibrating conveyor is an indispensable conveying device in the silk making equipment. During the long-term continuous work, the eccentric assembly of the vibrating conveyor will always wear out and cannot guarantee normal operation. At this time, it is necessary to disassemble the eccentric assembly for Easy to repair or replace. The weight of the eccentric assembly itself is relatively large, and the position of the vibrating conveyor is generally relatively low. The distance between the eccentric assembly located below the vibrating conveyor and the ground is even smaller, leaving a lot of space for maintenance personnel to carry out maintenance work. It is narrow and small, which leads to the fact that when the eccentric assembly is installed or disassembled, usually four or five maintenance personnel use the straps to pull up on both sides at the same time to facilitate installation. Such an installation process is not only time-consuming and laborious, but also has certain safety hazards. However, the jack provided in the workshop is too small and cannot complete the jacking work, which invisibly increases the difficulty of maintenance work and poses safety hazards.

Utility model content

The purpose of the utility model is to provide a jacking device for the eccentric assembly of the vibrating conveyor, which can be used in the small space of the eccentric assembly of the conveyor, and realize the jacking of the eccentric assembly by using the rotating torque.

In order to achieve the above object, the utility model adopts the following technical solutions:

A jacking device for an eccentric assembly of a vibrating conveyor, comprising a screw rod extending vertically, several nuts sheathed on the top of the screw rod, a support frame arranged at the lower part of the screw rod, and a screw driving device.

The support frame includes a base, a hollow cylinder arranged on the base and perpendicular to the base, a waist-shaped hole extending in the vertical direction is opened on the side wall of the hollow cylinder, and the screw rod is passed through the hollow cylinder .

The screw driving device includes a hollow tube sleeved on the outside of the screw and provided with internal threads, a steering wheel and a connecting rod between the steering wheel and the hollow tube and used to connect the steering wheel and the hollow tube. The empty pipe is threadedly connected with the screw.

Further, there are two nuts.

Further, a plane bearing is provided between the bottom end of the driving device and the top end of the support frame.

Further, the lower part of the screw rod is provided with a through hole along the horizontal direction, and a positioning pin is pierced in the through hole.

The beneficial effects of the utility model:

1) The utility model uses the relative movement of the screw rod and the hollow tube, so that the screw rod moves up and down to realize the jacking up of the eccentric assembly by the screw rod; due to the small height and small volume of the regular device, other regular devices and conveyors can be avoided. The problem of mismatching reduces the workload of the staff.

2) The utility model is equipped with a plane bearing between the driving device and the support frame, which can reduce the friction when the hollow tube in the driving device rotates, and is convenient for the staff to operate.

Detailed ways

A jacking device for the eccentric assembly of a vibrating conveyor, as shown in Figure 1-4, includes a screw rod 5 extending in the vertical direction, several nuts 6 sleeved on the top of the screw rod 5, and a support frame 1 arranged at the lower part of the screw rod 5 , and the screw driving device 4. In this embodiment, the nut 6 is provided with two, and the inside of the two nuts 6 are respectively positive and negative two helical wires. On the one hand, the nut 6 can play a locking role when the screw rod 5 reaches the corresponding position. Aspects can prevent the nut 6 from coming off.

The support frame 1 includes a base 11, a hollow cylinder 12 arranged on the base 11 and perpendicular to the base 11, a waist-shaped hole 13 extending in the vertical direction is provided on the side wall of the hollow cylinder 12, and the screw rod 5 passes through the hollow cylinder 12, and the inner diameter of the hollow cylinder 12 matches the outer diameter of the screw 5. The base 11 is placed horizontally on the ground, and the waist-shaped hole 13 on the side wall of the hollow cylinder 12 can be used as a position observation window for the screw rod 5, and the position of the bottom surface of the screw rod 5 can prevent the screw rod 5 and the hollow cylinder 12 from falling off.

The screw driving device 4 includes a hollow tube 43 sleeved on the outside of the screw 5 and provided with an internal thread, the steering wheel 41 and between the steering wheel 41 and the hollow tube 43 are used to connect the steering wheel 41 and the hollow tube 43 The connecting rod 42, the hollow tube 43 is threadedly connected with the screw rod 5. The hollow tube 43 with internal thread rotates driven by the steering wheel 41 and rotates relative to the screw 5 , thereby realizing the up and down movement of the screw 5 .

In this embodiment, a plane bearing 3 is provided between the bottom end of the hollow tube 43 of the screw driving device 4 and the top end of the hollow cylinder 12 of the support frame 1 . The plane bearing 3 can reduce the frictional force of the hollow tube 43 during rotation, thereby making the rotation easier.

In this embodiment, a through hole can be opened in the lower part of the screw rod 5 along the horizontal direction as required, and the positioning pin 2 is pierced in the through hole. Locating pin 2 can prevent screw rod 5 from rotating.

When in use, select the screw rod 5 suitable for the height of the eccentric assembly of the conveyor, insert it into the hollow cylinder 12 of the support frame 1, and adjust it to a suitable height for the device; the staff turns the steering wheel 41, and the steering wheel 41 drives the hollow tube 43 Rotate, the hollow tube 43 and the screw rod 5 rotate relatively, so that the screw rod lifts up the eccentric assembly; the staff observes the position of the bottom end of the screw rod 5 through the waist-shaped through hole 13 to prevent the screw rod 5 from falling off the support frame 1.

The above embodiments are only preferred embodiments of the jacking device for the eccentric assembly of the vibrating conveyor, and are not intended to limit the scope of protection of the present utility model. Those of ordinary skill in the art should understand that the modification or equivalent replacement of the technical solution of the utility model does not depart from the essence and scope of the technical solution of the utility model.
