Further, a pull ring is connected to the limit rod.
Further, the limiting rod is a threaded rod and is in threaded connection with the sleeve.
Further, a connecting rod is arranged between the two anti-slip mechanisms at the same side, and two ends of the connecting rod are fixedly connected with one sleeve respectively.
Further, a non-slip mat is arranged on the pedal of the ladder frame.
The utility model has the beneficial effects that: through the sleeve that sets up in the ladder frame bottom, the ladder frame is difficult to slide away or take place to empty when using, has improved the security performance of ladder frame, and the sleeve can be removed moreover and shows the universal wheel with the support column bottom, can make things convenient for laborsaving more like this when shifting the ladder frame.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model;
fig. 2 is a cross-sectional view of a sleeve according to the present utility model.
In the example drawings: the device comprises a 1-ladder frame, a 2-supporting column, a 3-sleeve, a 4-limiting rod, a 5-fixing hole, a 6-limiting hole, a 7-universal wheel, an 8-pull ring, a 9-connecting rod and a 10-pedal.
Detailed Description
For a clearer understanding of technical features, objects, and effects of the present utility model, a specific embodiment of the present utility model will be described with reference to the accompanying drawings.
Example 1
As shown in fig. 1-2, the utility model provides a site climbing ladder anti-skid device, which comprises a ladder frame 1, wherein anti-skid mechanisms are arranged at four corners of the bottom of the ladder frame 1, each anti-skid mechanism comprises a support column 2, a sleeve 3 and a limiting rod 4, the top of each support column 2 is fixedly connected with the corner end of the ladder frame 1, a fixing hole 5 and a limiting hole 6 are respectively arranged at the upper part and the lower part of the side surface of each support column 2, the axis of each fixing hole 5 is parallel to the axis of each limiting hole 6, each sleeve 3 comprises a large-diameter end and a small-diameter end with the same side wall thickness, the small-diameter end of each sleeve 3 is matched with the support column 2, the large-diameter end of each sleeve 3 is in contact with the ground, a universal wheel 7 is arranged in the large-diameter end of each sleeve 3, each universal wheel 7 is fixedly connected with the bottom of each support column 2, and one end of each limiting rod 4 is inserted into each limiting hole 6 after penetrating through the small-diameter end of each sleeve 3.
In this embodiment, a pull ring 8 is connected to the stop lever 4. The user can apply force to pull the limit rod 4 conveniently.
In this embodiment, the stop lever 4 is a threaded rod, and the stop lever 4 is in threaded connection with the sleeve 3. The risk of dropping and losing can be reduced by screwing the limiting rod 4.
In this embodiment, a connecting rod 9 is disposed between two anti-slip mechanisms on the same side, and two ends of the connecting rod 9 are fixedly connected with one sleeve 3 respectively. The user can control the positions of both sleeves 3 simultaneously by means of the connecting rod 9.
In this embodiment, a skid pad is provided on the tread 10 of the ladder frame 1. The frictional force of the footstep 10 can be increased to prevent the worker from slipping down when boarding the ladder 1.
The working principle of the utility model is as follows: after the ladder frame 1 is completely opened, the sleeve 3 on the support column 2 is moved, the limiting rod 4 is inserted into the limiting hole 6 on the support column 2, so that the sleeve 3 cannot move any more, the large-diameter end of the sleeve 3 is in contact with the ground, the ladder frame 1 can be ensured not to slide away easily, the gravity center is lowered, tilting is not easy to occur, when the ladder frame 1 needs to be transferred to a next place for working, the limiting rod 4 is pulled out, the sleeve 3 is controlled to move upwards along the support column 2 until the limiting rod 4 is inserted into the fixing hole 5 above the limiting hole 6, and at the moment, the universal wheels 7 at the bottom of the support column 2 are exposed, and the ladder frame 1 is convenient and labor-saving to move through the universal wheels 7.
