Description

Rivet type drag chain without tripping

Technical Field

The utility model belongs to the technical field of drag chains, and particularly relates to a rivet drag chain without tripping.

Background

At present, the connection modes of the drag chain on the market are mostly connected through bolts, nuts and pins, and the connection pieces are easy to loosen or trip due to the action of vibration and impact force in the movement process. When the connection is loose, the connection between the tow chain units may become unstable, possibly causing the chain links to disengage or the entire tow chain to break, thereby affecting the operation and safety of the machine or equipment. The conventional connection method requires regular checking of the fastening state of the connection member to ensure stability and safety thereof. This is a cumbersome task for large equipment or complex machines, which takes a lot of time and labor costs. At the same time, loosening or damage to the connection may require downtime for maintenance, resulting in production or work interruption.

The utility model discloses a rivet type drag chain without tripping, which mainly solves the problems of unstable connection mode and difficult maintenance of the existing drag chain.

In order to achieve the purpose, the utility model provides a non-tripping rivet type drag chain, which comprises drag chain units, wherein the number of the drag chain units is at least one, and the drag chain units are rotatably connected through rivets; the drag chain unit comprises two connecting plates, two cover plates and two separation plates, wherein the connecting plates are vertical and oppositely arranged, and the cover plates are horizontal and oppositely arranged.

Preferably, two mounting grooves are formed in the connecting plate, and the cover plate is mounted in the mounting grooves through the fixing assembly.

Preferably, the bottom of apron is provided with the installation piece, the both ends of division board are provided with the recess, slidable mounting has the division board between the apron.

Preferably, the connecting plate is provided with a slot and three connecting holes.

Preferably, a connecting part is arranged at one end of the connecting plate, two slotted holes are arranged at the connecting part, and adjacent drag chain units are connected through the connecting part and the slots.

Preferably, the fixing assembly comprises fixing blocks and limiting buckles arranged at two ends of the cover plate, and limiting protruding blocks matched with the limiting buckles are further arranged on the connecting plate.

Preferably, the drag chain device comprises a machine body and the drag chain, wherein the machine body is provided with a mounting position, and the drag chain is mounted in the mounting position.

The technical scheme provided by the utility model has at least the following technical effects:

1. high stability: the utility model adopts rivet type connection, and greatly enhances the strength and stability of connection through the fixation and structural design of the rivet. The locking structure of the rivet can effectively prevent the loosening or tripping of the connecting piece, and ensures firm connection between the towing chain units, thereby providing higher connection stability.

2. Friction and noise reduction: the rivet type connection adopted by the utility model can reduce friction between chain links in the traditional drag chain connection mode and reduce noise level in the drag chain working passing vehicle. The rivet connection mode reduces the friction area and friction points between the connecting pieces in the working process, so that the drag chain is more stable in the moving process, and the possibility of mechanical abrasion and noise generation is reduced.

3. Simplified maintenance: the rivet connection is more simplified in maintenance than the conventional connection. Rivet connections are highly reliable, reducing the need for frequent inspection and maintenance due to loosening or tripping of the connection. This reduces the workload of maintenance personnel in drag chain maintenance and reduces the need for downtime for maintenance.
