Because the tension maintainer includes the bucket, the movable lifting beam for connecting with the winch wire rope is mounted on the bucket lug of the bucket, the internal thread hole is opened in the center position of the bucket bottom of the bucket, the tension adjusting threaded tube is mounted in the internal thread hole, the tension spring is mounted in the bucket, the lifting cover that can slide up and down in the bucket is further mounted in the bucket above the tension spring, the steel wire rope hanging beam is arranged on the center of the top of the lifting cover, and the connecting steel wire rope between the tension maintainer and the permanent magnet hoist is hung on the permanent magnet hoist at one end and hung on the steel wire rope hanging beam of the lifting cover through the tension adjusting threaded tube and the tension spring at the other end, one aspect can effectively overcome the defect that the winch adopts the ratchet and pawl structure to prevent the winch wire rope from being loosened and rolled back, so that the cable sheath extrusion die can be pulled up and seated on the carriage bottom plate, and the friction force between the cable sheath extrusion die and the carriage bottom plate can be maintained, and the other aspect is that the tension maintainer does not affect the lifting operation of the cable sheath extrusion die using the winch. Because the pulling fixed pulley is further arranged in the middle part of the upright column, and the pulling fixed pulley is fixed on the upright column using the cantilever shaft, when the cable sheath extrusion die needs to be pulled from the front end of the carriage bottom plate to the middle part, the winch wire rope can be conveniently hung in the wheel groove of the pulling fixed pulley, so that the cable sheath extrusion die can be pulled to the middle part of the carriage below the cantilever beam using the winch, and the labor intensity of manual carrying of workers is reduced. Because the lifting cover is a circular lifting cover, the guide skirt cylinder extending downwards from the edge of the lifting cover is arranged in sliding fit with the inner wall of the bucket, so that the circular lifting cover slides up and down in the bucket more smoothly. Because the inner diameter of the guide skirt cylinder is 1-2 mm larger than the outer diameter of the tension spring, and the height of the guide skirt cylinder is greater than the pitch of the spring, the guide skirt cylinder can also limit the top of the tension spring, so that the tension spring is stressed more evenly, and the tension maintaining effect is better.The use of a hollow handwheel at the lower end of the tension adjusting threaded tube allows for convenient adjustment of the tension spring's stroke, thus meeting the constraint requirements of extrusion dies for cable sheaths of varying weights. The use of a manual winch or an electric winch driven by a battery, motor, and reducer simplifies operation and reduces labor. The carriage is composed of a floor, two side panels, a rear panel, and a front panel, with the front panel being a hinged movable panel connected to the floor. The height of the front panel is greater than the height from the floor to the lower edge of the wheels. This design allows for the folding down of the front panel to create a ramp when large dies placed on the ground need to be transferred into the carriage, facilitating loading. Attached Figure Description
[0012] The cable sheath extrusion mold transport vehicle of this utility model will be further described in detail below with reference to the accompanying drawings.
[0013] Figure 1 This is a schematic diagram of the overall structure of the cable sheath extrusion mold transport vehicle of this utility model;
[0014] Figure 2 This is an enlarged cross-sectional view of the tension retainer in the cable sheath extrusion die transport vehicle of this utility model;
[0015] Figure 3 This is a diagram showing the state of the cable sheath extrusion die transport vehicle when it pulls the cable sheath extrusion die. Detailed Implementation
[0016] like Figure 1 As shown, the cable sheath extrusion mold transport vehicle of this utility model includes a carriage, wheels 11, and a pusher handle 1. The carriage is also equipped with a mold stabilizing device to prevent the mold from moving inside the carriage. The mold stabilizing device includes a column 7 fixed to the floor of the carriage, a cantilever beam 3 fixed to the upper end of the column, a column fixed pulley 2 at the upper end of the column, a cantilever beam fixed pulley 4 at the front end of the cantilever beam, and a winch 6 on the column. The winch wire rope 3 passes around the column fixed pulley and the cantilever beam fixed pulley and hangs above the carriage. A tension retainer 14 and a permanent magnet lifter 12 are connected to the hanging end of the wire rope.
[0017] like Figure 2As shown, the tension maintainer comprises a bucket 19, a movable beam 24 for connecting with the winch wire rope is arranged on the bucket ear 25 of the bucket, an inner threaded hole 21 is arranged at the center position of the bucket bottom of the bucket, a tension adjusting threaded tube 22 is arranged in the inner threaded hole, a tension spring 20 is arranged in the bucket, the lower end of the tension spring is sleeved outside the tension adjusting threaded tube, a lifting cover 17 which can slide up and down in the bucket is further arranged above the tension spring in the bucket, a wire rope hanging beam 16 is arranged at the center of the top of the lifting cover, and the connecting wire rope 13 between the tension maintainer and the permanent magnet hoist is hung on the permanent magnet hoist at one end and hung on the wire rope hanging beam of the lifting cover at the other end through the tension adjusting threaded tube and the tension spring.
[0018] When the winch is used to prevent the wire rope from being rolled back, the length of the wire rope changes in a step-by-step manner, the cable sheath extrusion die is lifted or separated from the bottom of the carriage bottom to lose the friction force, or is completely seated on the carriage bottom, the wire rope loses the upward pulling force on the cable sheath extrusion die, and it is impossible to both pull the cable sheath extrusion die upward and ensure that the cable sheath extrusion die is seated on the carriage bottom to maintain sufficient friction force between the cable sheath extrusion die and the carriage bottom. The tension maintainer in the utility model can overcome the foregoing defects of the winch, adjust the length of the wire rope using the tension spring when the length of the wire rope changes in a step-by-step manner, and thus both pull the cable sheath extrusion die upward and ensure that the cable sheath extrusion die is seated on the carriage bottom, so that the cable sheath extrusion die is constrained and stabilized. When the winch is used to lift the cable sheath extrusion die, the winch wire rope pulls the bucket to move upward, the lifting cover slides relative to the bucket under the action of the gravity of the cable sheath extrusion die itself, the tension spring is compressed, and when the bucket is lifted to a certain stroke, the lifting cover is seated on the upper end of the tension stroke adjusting threaded tube under the action of the gravity of the cable sheath extrusion die itself, the tension stroke adjusting threaded tube directly transmits the lifting force to the lifting cover, and thus the effect of directly connecting the permanent magnet hoist and the winch wire rope is achieved.
[0019] The tension maintainer does not affect the lifting operation of the cable sheath extrusion die using the winch.
[0020] Preferably, the lifting cover is a circular lifting cover, a guide skirt 18 extending downward relative to the lifting cover and slidingly matched with the inner wall of the bucket is arranged at the edge of the lifting cover.
[0021] Preferably, the inner diameter of the guide skirt is 1-2 mm larger than the outer diameter of the tension spring, and the height of the guide skirt is greater than the pitch of the spring. The height of the guide skirt is the distance from the lower edge of the guide skirt to the lower surface of the lifting cover. In this way, the guide skirt can serve as a stabilizing device of the tension spring to prevent the tension spring from tilting when compressed.
[0022] A hollow screw hand wheel 23 is arranged at the lower end of the tension adjusting threaded tube.
[0023] The winch is a hand winch or an electric winch driven by a battery, an electric motor and a speed reducer.
[0024] As shown in Figure 3 The pulling fixed pulley 5 is fixed on the stand by a cantilever shaft.
[0025] The vehicle compartment is composed of a bottom plate 15, two side compartment plates 9, a rear compartment plate 8 and a front compartment plate 10. The front compartment plate is a movable compartment plate connected to the bottom plate by a hinge. The height of the front compartment plate is greater than the height from the bottom plate to the lower edge of the wheel.
[0026] When it is needed to load the heavy cable sheath extrusion die from the ground into the vehicle compartment, the front compartment plate can be opened, the upper end of the front compartment plate is in contact with the ground, a transportation ramp is built between the ground and the bottom plate of the vehicle compartment, the winch steel wire rope hanging from the cantilever beam fixed pulley is hung into the wheel groove of the pulling fixed pulley, the winch is started, the cable sheath extrusion die is pulled, and the cable sheath extrusion die is slid into the vehicle compartment through the front compartment plate ramp. During the movement of the cable sheath extrusion die transport vehicle, the two sides of the front compartment plate are fixed with the two side compartment plates respectively, so that the front compartment plate is kept in Figure 1 the upright state as shown.
