Tire locking brake for electric power construction transfer vehicle

Abstract

The invention provides a tire locking brake for an electric power construction transfer vehicle. A fixed block and a sliding shaft of the tire locking brake are in clearance fit. The upper end of the sliding shaft is fixedly connected with a drive plate, and clamping supports used in pairs are hinged to the lower end of the sliding shaft. A sleeve is fixed to the upper end face of the drive plate, a telescopic rod with a handle is arranged in the sleeve, and a locking rotary knob is arranged at the upper end of the sleeve. A reset spring A is arranged between the two clamping supports, and reset springs B are connected between the two clamping supports and the lower end of the fixed block respectively. Upper limiting grooves and lower limiting grooves are sequentially formed in the side wall of a through hole in the vertical direction. At least two sets of upper limiting grooves and lower limiting grooves are evenly formed in the side wall of the through hole in the circumferential direction. A ball pin capable of matching the upper limiting grooves and the lower limiting grooves is arranged on the outer side wall of the sliding shaft, a radial mounting groove is formed in the outer side wall of the sliding shaft, and the ball pin is arranged in the radial mounting groove through a reset spring C. The brake can lock and unlock tires of the transfer vehicle.

Description

technical field [0001] The invention relates to an electric construction transfer vehicle, in particular to a wheel-locking brake for an electric construction transfer vehicle. Background technique [0002] During electric power construction, most of them need to work in the field, and they need to carry work tools during the work. Due to the complex terrain in the field, some places cannot enter the vehicle, and the work tools can only be brought to the work site by rotating the car. However, the transfer vehicles currently used are all It is a conventional push-pull trolley on the market. The tires in this trolley cannot be locked. When working in the field, it is affected by factors such as terrain and wind, and it is easy to cause the trolley to move by itself, which may cause the trolley to tip over and damage the work equipment. This is The deficiencies of existing technology. Contents of the invention [0003] The technical problem to be solved by the present inven...
