Detailed Description

The portable belt lifting machine provided by the present invention will be further described with reference to the accompanying drawings and embodiments.

Because the space of the replacement position of the carrier roller is narrow and is not suitable for large-scale and heavy equipment construction, the carrier roller needs to be replaced frequently, and the position for replacing the carrier roller is changed continuously. Therefore, a portable, reliable and quick jacking tool needs to be designed, so that the labor intensity of roller replacement can be greatly improved. The utility model discloses an aluminum alloy makes, and whole weight is only 16KG, and a workman can carry.

As shown in figure 1, the utility model provides a portable belt jacking machine includes lower part climbing mechanism 1 and upper portion jacking frame 2, lower part climbing mechanism 1 and 2 welded connection of upper portion jacking frame

As shown in fig. 2, the utility model discloses a lower part climbing mechanism includes base 101, activity tripod 102 and trapezoidal screw rod 103, constitutes a triangle-shaped climbing mechanism that can the jacking jointly, and bottom trapezoidal screw rod 103 is TR16 4 trapezoidal lead screw, and it divide into two sections, and the combination is in the same place, and the right is the dextrorotation lead screw, and the left side is the levogyration lead screw, and single lead screw length is 1394mm, and levogyration lead screw and dextrorotation lead screw link together at the middle part position with the nut of two flanged, the nut and the lead screw of flanged bore the through hole, only rotate with diameter 6mm round pin. The end of the trapezoidal spiral screw rod 103 is a hexagon with the opposite side size of 10MM, and is fixed on the base 101, the screw rod 103 can be rotated by a standard sleeve, and because the left-handed screw rod and the right-handed screw rod are rigidly connected together, when the sleeve at one end is rotated, the leftmost screw rod can be always driven when the screw rod is rotated from the rightmost side. One end of the movable tripod 102 is connected with the screw rod 103 through the roller mechanism, the other end of the movable tripod is fixed on the base 101, the screw rod 103 rotates, the two ends of the left-handed screw rod and the right-handed screw rod are fixed, so the movable tripod 102 drives the movable end of the movable tripod to move from the two ends to the middle through the roller mechanism, the jacking function is achieved, the limiting device is arranged on the base 101, and when the roller mechanism moves to the limiting device, the highest height of the lower jacking mechanism is 400 MM.

As shown in fig. 3, the upper jacking frame of the present invention comprises a support 201 and a movable portion 202, wherein the movable portion 202 is arranged oppositely, and adopts a structure similar to an inverted V-shape with one side fixed and one side movable, wherein the dotted line portion in fig. 3 is the position where the movable portion 202 is initially installed, the height is 196MM, and the support height 102MM is subtracted; the height 265MM +94MM =359MM at pre-installation of the optimal section of the entire belt jack is below the belt's lowest position by the floor height 369MM, which ensures that the jack mechanism can be placed under the belt for operation.

The utility model discloses an among the concrete operation process, the jacking machine is put behind under the belt, with the rotatory trapezoidal lead screw of an electric spanner cooperation sleeve, whole jacking machine is with regard to quick jacking belt, reachs predetermined high after-fixing lead screw, carries out the bearing roller and changes.

After the carrier roller is replaced, the electric wrench rotates reversely, the whole jacking machine is lowered to the initial height, the jacking machine is taken out, and the next working position is moved.

A workman utilizes the utility model discloses 10 bearing rollers of change belt feeder in succession have only used 4 hours, and 2 former workers utilize jack cooperation operation, need about 8 hours, and because the jack removes more difficultly, workman intensity of labour is very big moreover, the utility model provides a pair of portable belt jacking machine only has 16 kilograms, and a workman just can carry, very convenient and fast, and simple structure, and difficult trouble that produces, the same work load, 25% in the former man-hour of operating time have improved work efficiency greatly, have reduced the cost of labor of changing the bearing roller.
