the arrangement of the angle adjusting mechanism enables the position of the guide rod on the chain to be changed through operation of the crank when the integral bracket is manually pushed to a target position, so that the angle adjustment of the swing arm is realized, and the operation is time-saving and labor-saving; when the wire feeding mechanism does not need to work, the wire feeding mechanism can move by means of the following wheels, and extra heavy load is avoided.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural view of the wire feeding mechanism of the present invention.
Fig. 3 is a schematic structural view of the middle wire feeding mechanism of the present invention in a high position state.
In the attached drawing, the device comprises a bracket 1, a support 2, a turntable 3, a support 4, a pair of rollers 5, a swing arm 6, a chain 7, an adjusting rod 8, a guide rail groove 9, a guide rod 10, a crank 11, a threading channel 12, a threaded column 13, a threaded through groove 14, a travelling wheel 15, a pushing handle 16 and a following wheel.
Detailed Description
The utility model relates to a threading device for road construction, include the line reel and send line mechanism, the line reel include support 1 and carousel 2, send line mechanism to include support 3 and pair roller 4, its characterized in that, 1 bilateral symmetry of support articulated have swing arm 5, the end of swing arm 5 is articulated with the 3 upper ends of support that send line mechanism, still be provided with swing arm 5's angle adjusting mechanism on the support 3.
In the specific embodiment, as shown in fig. 1 to 3, in fig. 1, which is an initial state, an operator pushes the whole device to a target position by means of a push handle 15, and then adjusts the angle of the swing arm according to the height of a threading position as required, the angle adjustment mechanism includes chain transmission mechanisms on both sides of a bracket 1, the chain transmission mechanisms are vertically arranged, the swing arm 5 is provided with an adjustment rod 7 matched with a chain 6 of the chain transmission mechanism, the adjustment rod 7 is provided with a guide rail groove 8 along the length direction, and a guide rod 9 in sliding fit with the guide rail groove 8 is fixed on the chain 6; the bracket 1 is provided with a crank 10 connected with a chain drive. As shown in fig. 3, when the adjustment is required to be performed to a high place, the crank 10 is rotated, the guide rod 9 on the chain 6 is moved upwards through the chain transmission mechanism, at this time, the guide rod 9 slides along the guide rail groove 8 to compensate the movement of the guide rod in the length direction relative to the swing arm 5 when the guide rod moves upwards, the swing arm 5 drives the wire feeding mechanism to move upwards, and finally the wire feeding mechanism is placed on the operation surface; conversely, when adjustment to the lower position is required, the handle 10 is reversed.
