BACKGROUND

[0002] The transmission of polyurethane spraying winding heat preservation pipe is generally completed by tire type conveying line, that is, the heat preservation pipe is transported forward spirally under the extrusion of the relatively arranged tire rotation.

[0003] Although the tire type conveying line can convey the heat preservation pipe, the heat preservation layer on the heat preservation pipe will crack due to the rolling of the tire on the heat preservation layer when the heat preservation layer is not completely solidified, thereby affecting the quality of the heat preservation pipe.

[0004] In addition, when the steel pipe is discharged after spraying polyurethane powder, the first tire end of the tire type conveying line may be knocked due to improper height adjustment of the conveying line, which affects the quality of the un-solidified heat preservation layer.

[0005] Therefore, it is necessary to provide a large diameter polyurethane spraying heat preservation pipe belt type conveying line with stable conveying, reduced risk of heat preservation layer cracking and easy implementation. UTILITY MODEL CONTENTS

[0006] The utility model aims to overcome the shortcomings of the prior art and provide a high stability large diameter polyurethane spraying heat preservation pipe belt type conveying line with stable conveying, reduced risk of heat preservation layer cracking and easy implementation.

[0007] The utility model solves the technical problem by adopting the following technical scheme:

[0008] The high stability large diameter polyurethane spraying heat preservation pipe belt type conveying line comprises a base, a supporting conveying unit and a hydraulic opening and closing unit. The supporting conveying units are uniformly distributed along the length direction of the base. Each supporting conveying unit is horizontally inclined on the base. The hydraulic opening and closing unit is arranged on the supporting conveying unit at the first end of the base to drive the conveying belt to open and close.

[0009] Furthermore, the supporting conveying unit comprises a base, a bracket, a driving roller, a driven roller, a bearing seat and a conveying belt. The base is mounted on the base. The brackets are arranged at the top of both ends of the base. The driving roller and the driven roller are mounted on the brackets through the bearing seat. The driving roller is driven to rotate by a speed reducer motor. The conveying belt is wound around the driving roller and the driven roller.

[0010] Moreover, the base includes two channel steels with openings facing outward, a horizontal track plate is provided on the upper end groove wall of each channel steel, a bracket is provided on the track plate, and slide grooves sliding on the track plate are provided on both sides of the bottom plate of the bracket. A hydraulic cylinder is provided in the middle position of the bottom of the bracket, the rear end of the hydraulic cylinder is fixed on the end plate between the two channel steels, and the cylinder rod at the front end of the hydraulic cylinder is connected to the connecting plate located at the bottom of the bracket.

[0011] The advantages and positive effects of the utility model are:

[0012] 1. This highly stable large-diameter polyurethane spray insulated pipe belt conveyor line effectively avoids the problem of tires crushing the surface of the insulated pipe by designing the traditional tire-type conveying method as a conveyor belt supporting conveying method, thereby ensuring product quality. At the same time, when the pipe is introduced into the pipe, the supporting conveying unit located at the head end of the base can adjust the opening and closing of the conveyor belt through the hydraulic opening and closing unit, thereby achieving the purpose of stable introduction and supporting conveying of the insulated pipe through the opening and closing of the conveyor belt.

[0013] 2. The design of this utility model is scientific and reasonable, and it has the advantages of smooth transportation, reduced risk of cracking of the insulation layer, and easy implementation. It is a highly innovative, highly stable, large-diameter polyurethane spray insulation pipe belt conveyor line. BRIEF DESCRIPTION OF THE DRAWINGS
