Description

Technical Field

[0001] The utility model relates to the technical field of installation of multi-V belt roller conveyors in the logistics industry, in particular to a handheld roller installation pliers. Background Art

[0002] With the development of the times, mechanical logistics installation workshops are widely used. Mechanical logistics installation workshops are workshops dedicated to the installation, commissioning and maintenance of logistics equipment. Its main task is to provide support for the logistics system and ensure the normal operation of various logistics equipment. Mechanical logistics installation workshops include conveyors and other equipment. During the installation of conveyors, multi-V belt rollers need to be installed. In logistics conveying equipment, the function of multi-V belt rollers is to drive and convey the materials from the feeding device through multiple rollers, and convey the materials to the designated location or the next process flow. Due to the characteristics of high transmission efficiency and low noise of multi-V belts, multi-V belt rollers are widely used in logistics conveying equipment.

[0003] The existing multi-V belt roller conveyor requires two installers to install. During the installation of the multi-V belt roller conveyor, the two installers first put the multi-V belt on the first roller to form the first roller, and then fix the bolts at both ends of the first roller. Then, they screw the bolts on the end of the adjacent second roller without the multi-V belt (no need to tighten), and put the multi-V belt connected to the first roller on the multi-V belt end of the roller, and then put the multi-V belt connected to the next adjacent roller on. Next, one of the installers needs to manually increase the distance between the two rollers and align them with the installation holes, and the other installer randomly fixes the bolts. Repeat the above actions to complete the installation of all rollers, and finally adjust and tighten the bolts diagonally. The above action of increasing the distance between the two rollers is time-consuming and labor-intensive, and has certain risks. For this purpose, a handheld roller installation pliers has been developed. Utility Model Content

[0029] The support block 3 is installed on the top of the first stainless steel handle 4 and the top of the second stainless steel handle 5. The support block 3 is made of PU polyurethane material. The support block 3 in the technical solution of the present application can also be called a support PU block. The first stainless steel handle 4, the second stainless steel handle 5 and the support block 3 are connected by screw connection, and a welding connection method can also be used according to actual use needs. The advantage of the screw connection method is that the support PU block can be easily removed when the support PU block is damaged;

[0030] The support block 3 includes a support block body 301, a support block top end surface 302, a support block groove 303, a support block connection hole 304 and a support block bottom end surface 305;

[0031] The support block 3 is designed to match the contour of the outer wall of the roller, that is, when the support block 3 contacts the outer wall of the roller, the support block groove 303 of the support block 3 is in a fit with the outer wall of the roller. At this time, the operator applies pressure to the first stainless steel handle 4 and the second stainless steel handle 5, thereby utilizing the lever principle, and the pressure applied by the operator is transmitted to the support block 3, and the support block 3 generates a driving force on the roller, thereby achieving the effect of increasing the distance between the two rollers.

[0032] The support block groove 303 is arranged on the outer wall of the support block body 301, and the support block body 301 is located at one end of the outer wall of the support block groove 303 and is provided with the support block top end face 302, and the support block body 301 is located at the other end of the outer wall of the support block groove 303 and is provided with the support block bottom end face 305. The technical solution of the present application adopts the design that the support block top end face 302 and the support block bottom end face 305 are located in the support block groove 303, and its purpose is that when the support block groove 303 contacts the outer wall of the roller, the support block top end face 302 and the support block groove 303 can be stuck on the outer wall of the roller, so as to realize the rapid contact between the support block groove 303 and the outer wall of the roller, making it easier to find the contact position between the support block groove 303 and the outer wall of the roller.

[0033] The support block connecting hole 304 is provided in the middle of the support block body 301, and the support block connecting hole 304 is used for bolt connection.
