Abstract
The invention relates to an improvement of automobile rain detection test conveying equipment, in particular to a pre-tensioning device for a conveyor. The pre-tensioning device is provided with a sliding seat, a support sliding block, a pull rod and a nut, wherein one end of the pull rod is provided with a shaft ring, and the other end of the pull rod is provided with a screw rod; the nut is arranged on the screw rod of the pull rod; the pull rod is formed by the shaft ring and the support sliding block; particularly, a spring is arranged on the pull rod at a shaft neck arranged at the outer side of the sliding seat; one end of the spring is contacted with the outer side of the sliding seat, and the other end of the spring is contacted with the nut arranged on the screw rod. The pre-tensioning device for the conveyor solves the problem that the accident of machine damage is easily caused once a plate chain of the existing single-plate chain pull-type conveyor is blocked, thus being mainly used for improving the existing single-plate chain pull-type conveyor.
Description
(i) technical field: the present invention relates to automobile and drench with rain and detect the improvement of test load transfer device, is a kind of conveyer pre-tensioning device.
(ii) background technology: automobile drenches with rain and detects test facility and be provided with single plate chain trailing type conveyer, and single plate chain trailing type conveyer is provided with stretching device, and stretching device is comprised of slide, supporting slide block and adjusting screw(rod); The problem that prior art single plate chain trailing type conveyer exists is: stretching device is rigid tension structure, after stroke of tension adjustment is determined, supporting slide block is fixed, once the operation of plate chain is subject to jam, or driving shear pin ruptures or reducing motor is impaired.
(iii) summary of the invention: once object of the present invention is exactly will solve the existing plate chain of existing single plate chain trailing type conveyer to be subject to the problem that engine-damaged accident easily occurs jam, provide a kind of conveyer pre-tensioning device.
Concrete scheme of the present invention is: a kind of conveyer pre-tensioning device, it is provided with slide, supporting slide block, pull bar and nut, and one end of pull bar is provided with the axle collar, and the other end of pull bar is provided with screw rod, nut is mounted on the screw rod of pull bar, and pull bar is to form and install with the axle collar and supporting slide block; It is characterized in that: pull bar is positioned on the axle journal outside slide spring is installed, one end of spring is to touch with the outer layback of slide, and the other end of spring is to contact with the nut on screw rod.
The present invention compares with existing single plate chain trailing type conveyor straining device, the present invention is provided with spring on the pull bar in stretching device, spring is mounted in the outside of stretching device slide, the stroke of stretching device supporting slide block is to be regulated by the nut on pull bar, pull bar, the interaction of nut and slide makes spring have certain pretension, can meet the tension force pretension of single plate chain, when single plate chain is subject to jam, the compression surplus of spring also can be alleviated the limit tension of single plate chain, once avoid the existing single plate chain of original design to be subject to the problem that engine-damaged accident easily occurs jam, the present invention is simple in structure, operate steadily, cheap, once the present invention preferably resolves the existing plate chain of existing single plate chain trailing type conveyer and is subject to the problem that engine-damaged accident easily occurs jam.
(iv) accompanying drawing explanation:
Fig. 1: structural front view of the present invention;
In figure: 1-supporting slide block, 2-axle collar, 3-pull bar, 4-slide, 5-screw rod, 6-spring, 7-nut.
(v) the specific embodiment:
Embodiment: (referring to Fig. 1) a kind of conveyer pre-tensioning device, it is provided with slide 4, supporting slide block 1, pull bar 3 and nut 7, one end of pull bar 3 is provided with the axle collar 2, the other end of pull bar 3 is provided with screw rod 5, nut 7 is mounted on the screw rod 5 of pull bar 3, and pull bar 3 is to form and install with supporting slide block 1 with the axle collar 2; Particularly: pull bar 3 is positioned on the axle journal in slide 4 outsides spring 6 is installed, one end of spring 6 is to touch with the outer layback of slide 4, and the other end of spring 6 is to contact with the nut 7 on screw rod 5.
