Description

Technical Field

[0001] The utility model relates to a lifting machine for composite pipes. Background Art

[0002] A composite hose is usually composed of a flexible tube body in the middle and connectors at both ends, and the connectors are usually metal parts with metal connectors provided at both ends. This results in very heavy large-size composite hoses, especially the connectors at both ends are relatively heavier. It is time-consuming and laborious for employees to transfer these large-size composite hoses, and there is also a risk of injury.

[0003] For some existing lifting mechanisms for pipe materials, a lifting rod protruding forward is usually provided on one side of a movable base. This method is not suitable for lifting heavy composite pipes and easily causes the lifting mechanism to lean forward and tip over; in order to ensure that the lifting mechanism does not lean forward, counterweights need to be added on the other side to maintain balance, but this method undoubtedly increases the burden on the user to push the lifting mechanism; at the same time, since the pipe material is usually circular, a matching limit groove needs to be provided on the lifting rod. Therefore, even when the lifting rod descends to the lowest point, there is a protrusion with a certain height at its front end, making it necessary for the user to manually and laboriously lift the composite pipe to a certain height into the limit groove. Summary of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide a lifting machine for composite pipes to solve the above problems.

[0005] The utility model adopts the following scheme:

[0006] The present application provides a lifting machine for composite pipes, including a base provided with moving wheels, a lifting mechanism provided on the base, and a lifting rod connected to the lifting mechanism and having a limit groove; the base includes a seat body part and a support rod part connected to the seat body part and protruding forward; the lifting mechanism is provided on the seat body part; first moving wheels are provided on both sides of the bottom of the seat body part; a second moving wheel is provided at the front end of the support rod part; and a placement groove is provided on the support rod part, and when the lifting rod descends to the lowest point, it is placed in the placement groove.

[0007] Further, when the lifting rod is placed in the placement groove, the upper end surface of the front end of its limit groove is not higher than the height of the second moving wheel.

[0008] Further, it further includes a chassis provided on the seat body; a moving groove for the lifting rod to move is provided on the chassis, and the limit groove is located outside the chassis.

[0009] Further, a handrail is provided on the chassis.

[0010] Further, an operation console is provided on the chassis.

[0011] Further, the lifting mechanism includes a motor, a first sprocket connected to the motor, a second sprocket disposed above the first sprocket, and a chain connecting the two sprockets; one end of the lifting rod is connected with a slider, and the slider is connected to the chain.

[0012] Further, the lifting rod is coated with POM plastic steel.

[0013] Further, when the lifting machine is placed on a horizontal ground, at least the support rod portion inclines forward and downward.

[0014] By adopting the above technical solutions, the following technical effects can be achieved by the present utility model:

[0023] Embodiment

[0024] Combined with Figures 1 to 4 As shown, this embodiment provides a lifting machine for composite pipes, including a base provided with moving wheels, a lifting mechanism arranged on the base, and a lifting rod 5 connected to the lifting mechanism and having a limit groove 11; the base includes a seat body part and a support rod part 4 connected to the seat body part and protruding forward; the lifting mechanism is arranged on the seat body part; first moving wheels 6 are arranged on both sides of the bottom of the seat body part; a second moving wheel 7 is arranged at the front end of the support rod part 4; and a placement groove 10 is arranged on the support rod part 4, and when the lifting rod 5 descends to the lowest position, it is placed in the placement groove 10.

[0025] The three moving wheels are arranged in a triangular distribution. The support rod part 4 is arranged directly below the lifting rod 5, providing better support for the lifting rod 5 when lifting the composite pipe, and effectively avoiding the situation that the lifting machine topples forward; at the same time, the arrangement of the placement groove 10 on the support rod part 4, when the lifting rod 5 descends to the lowest position, it is placed in the placement groove 10. Since the second moving wheel 7 is arranged at the front end of the support rod part 4, workers can manually roll the composite pipe to the limit groove 11 of the lifting rod 5 by using the second moving wheel 7, without manually lifting the composite pipe completely off the ground, reducing the burden on workers.

[0026] Specifically, in this embodiment, as Figure 2 shown, it includes a machine case 3. The seat body part includes a first seat body part 1 connected to the rear side of the bottom of the machine case 3, and a second seat body part 2 connected to the front side of the bottom of the machine case 3; two of the first moving wheels 6 are arranged on both sides of the lower end surface of the first seat body part 1; the support rod part 4 is arranged in the middle of the front end of the second seat body part 2. A moving groove 12 for the lifting rod 5 to move is arranged on the front surface of the machine case 3, and the limiting groove 11 of the lifting rod 5 is located outside the machine case 3. The lifting mechanism is arranged on the seat body part and is located inside the machine case 3; it includes a motor 8, a first sprocket 15 connected to the motor 8, a second sprocket 16 arranged on the machine case 3 above the first sprocket 15, and a chain 9 connecting the two sprockets; one end of the lifting rod 5 is connected with a slider 17, and the slider 17 is connected to the chain 9. The forward and reverse rotation of the motor 8 drives the slider to move up and down through the transmission of the sprocket and the chain 9, and then drives the lifting to move up and down. An armrest 13 is arranged on the upper end surface of the machine case 3 for workers to push the lifter; and an operating platform 14 is arranged on the upper end surface of the machine case 3 to facilitate workers to control the lifting mechanism. In this embodiment, the lifting rod 5 is coated with POM plastic steel, which can effectively prevent scratching the composite hose.

[0027] Preferably, when the lifting rod 5 is placed in the placement groove 10, the upper end surface of the front end of its limiting groove 11 is not higher than the height of the second moving wheel 7; at the same time, when the lifter is placed on the horizontal ground, at least the support rod part 4 inclines forward and downward. Specifically, when the outer diameters of the two moving wheels are the same, the installation position of the axis of the second moving wheel 7 is higher than the installation position of the axis of the first moving wheel 6; or, when the installation heights of the axes are the same, the outer diameter of the second moving wheel 7 is smaller than the outer diameter of the first moving wheel 6, so that when the lifter is on the horizontal ground, the support rod part 4 inclines forward and downward, so as to facilitate workers to better use the second moving wheel 7 to manually roll the composite pipe onto the limiting groove 11 of the lifting rod 5 without manually lifting the composite pipe completely off the ground, reducing the burden on workers.
