Abstract
Description
Technical Field
[0001] The invention relates to the technical field of PE pipe inspection well production, and more particularly to a production winding device for an eccentric inspection well. Background Art
[0002] At present, the production method of PE pipe inspection wells basically adopts the fixed pressure wheel single-point winding method. This production method is effective for parallel pipes, but there will be great problems for tapered inspection wells, mainly reflected in the transition tapered area between the wellbore and the well chamber. The fixed pressure wheel crimping of this part cannot achieve follow-up force application, which often causes weak adhesion of PE material and uneven wall thickness of the inspection well. Especially for eccentric inspection wells, the winding of PE material in the transition area is more difficult, and even requires manual pressure application by production personnel, which directly affects the output and product quality of PE eccentric inspection wells and brings many difficulties to production. Summary of the Invention
[0003] The present invention provides a winding device for a PE eccentric inspection well, which is used to solve the technical problems in the prior art of weak adhesion of PE materials, uneven wall thickness of eccentric inspection wells and defects caused by a single crimping point and inability to follow the shape of the crimping.
[0004] The present invention is implemented by the following technical solution: a winding device for a PE eccentric inspection well, comprising: a fixed support mechanism, a sliding wheel chain mechanism, and a counterweight mechanism, wherein the fixed support mechanism is installed on the same side of the extruder of the production equipment, the movable hook (3) of the sliding wheel chain mechanism is connected to the fixed hook (2) of the fixed block (1), the sliding wheel chain mechanism is wound through the eccentric inspection well production mold, the chain of the sliding wheel chain mechanism is wound around the fixed pulley (13) of the fixed mechanism, and the chain hook (12) of the sliding wheel chain mechanism is connected to the counterweight (11) at the other end.
[0005] As a preferred embodiment of the present invention, the fixed support mechanism comprises: a fixed block (1) installed below the PE discharge port of the extruder, a fixed hook (2) provided on the fixed block (1) and connectable to a movable hook (3), a fixed support base (9) installed behind the discharge port of the extruder, a fixed support (10) provided at the center of the base (9), two fixed pulleys (13) installed above the support (10), the PE material enters the working area of the mold and the sliding wheel group from the discharge port through the chain locked by the fixed block, and the support (10) and the fixed pulley (13) are used to constrain the running trajectory of the chain (4).
[0006] As a preferred solution of the present invention, the sliding wheel group chain mechanism includes: a movable hook (3) located at the front end is connected to the sliding chain (4), the two pulleys (5) are connected by a connecting shaft (6) and are limited by a fixed end (8) to form a pulley group, the middle part of the connecting shaft (6) is pressed with the adjustment block (7) to fix the pulley group at any position on the chain (4), and the end of the chain (4) is provided with a chain hook (12) that can be connected to the counterweight block. The winding device of the present invention can apply multiple pulley groups, and a reasonable spacing distance is selected between two pulley groups according to the diameter of the production mold.
[0007] As a preferred embodiment of the present invention, the pulley (5) of the sliding wheel group chain mechanism is made of high-temperature resistant polytetrafluoroethylene material. The sliding wheel group chain mechanism adopts a chain structure in order to meet the requirements of tensile pressing strength and greater freedom of bending deformation in the longitudinal direction of the mold pressing movement. The sliding wheel group chain mechanism adopts an adjusting block (7) to fix the pulley group and the chain (4) in order to meet the requirements of tensile pressing strength and greater freedom of bending deformation in the transverse direction of the mold pressing movement. The sliding wheel group chain mechanism can perform an embracing multi-point winding pressing movement of more than half a circle along the mold surface during the force pressing process. For the irregular vertebral body part of the eccentric inspection well transition, it can be tightly wound according to the mold surface to provide sufficient pressing strength and pressing area.

[0009] The beneficial effects of the present invention are: the present invention utilizes a sliding wheel chain mechanism to adopt a multi-point wrapping winding method, which is more uniform in force compared to the single-point crimping winding of the existing production technology, and utilizes gravity counterweights to provide winding pressure, which is more reasonable compared to the single pressure of the existing production technology. The chain and pulley group structure provides lateral and longitudinal degrees of freedom, so that the PE material can be fully attached to the mold surface, solving the problem of insufficient crimping in the irregular vertebral transition zone of the eccentric inspection well.

It has the advantages of low equipment cost and strong product applicability. BRIEF DESCRIPTION OF THE DRAWINGS
