Abstract
The utility model relates to a work ladder being convenient to move, which comprises a ladder mounting bracket and an inclined ladder bed which is connected with the ladder mounting bracket, wherein the inclined ladder bed is fixedly provided with a stop device; the stop device comprises a crank, a connecting rod and a rocker, wherein the connecting rod is hinged with one end of the crank; the rocker is hinged to one end of the connecting rod; the crank and the rocker are connected with the inclined ladder bed through a lug with a hole and are hinged with the lug with the hole; the lower end of the rocker is provided with pulleys; the crank is fixedly provided with a handle; the pulleys can be driven to move up and down by wrenching the handle; the coupling end of the crank and the connecting rod is fixedly provided with a limit stop. Through additionally arranging the stop device on the work ladder, as long as the handle is wrenched, the conversion between the pulleys and fixed supporting feet can be realized, so that the ladder can be stably placed when working and the rapid conversion of the states of a transfer place is realized. The work ladder is time-saving and labor-saving and is especially suitable for places that inspection equipment, maintenance equipment and the like of which the positions need to be frequently changed.
Description
Technical field
The utility model relates to a kind of working stand of conveniently moving.
Background technology
When we carry out work and field maintenance, working stand is seen everywhere, and at present common have two kinds of forms: a kind of is not have wheel, and ladder contacts with ground by four fixed feet, this ladder is in work and all place during inoperative steadily, but mobile or transfer location is inconvenient; Another kind is to replace four fixed feet with four wheels, and two adjustable support legs are installed on the next door of two wheels therein, during work, screw off leg, near two wheel support ground replacing; When shifting the place, the spin-up leg makes it built on stilts, and at this moment, the four wheels kiss the earth is convenient to move.Since waste time and energy during the adjustable supports rotation, and adjustable supports is in the course of the work, has various uncertain factors, out of control easily, cause dangerous the generation.
The utility model content
Technical problem to be solved in the utility model provides a kind of working stand of conveniently moving.
The utility model adopts following technical scheme:
The utility model comprises terraced fixed mount and the inclined ladder frame that is connected with terraced fixed mount, it is characterized in that on the inclined ladder frame, being set with stop device, described stop device comprise crank, with the hinged connecting rod of crank one end and with the hinged rocking bar of connecting rod one end; Described crank is connected with the inclined ladder frame by auricle with holes with rocking bar and is hinged with auricle with holes, be provided with pulley in described rocking bar lower end, on crank, be set with handle, pull handle and can drive pulley and move up and down, be set with positive stop at described crank and connecting rod link.
Described stop device is symmetricly set on two inclined ladder framves.
Good effect of the present utility model is as follows:
The utility model is by increasing stop device, as long as pull handle, just can realize the conversion of pulley and fixed feet, steadily place quick conversion when realizing ladder work with the transfer location state, time saving and energy saving, be particularly useful for checking, maintenance of equipment etc. needs the frequent place of changing the position.
Description of drawings
Fig. 1 is a structure schematic side view of the present utility model;
Fig. 2 is the utility model working stand mobile status schematic diagram.
In the accompanying drawings: 1 handle, 2 cranks, 3 connecting rods, 4 rocking bars, 5 inclined ladder framves, 6 fixed feet, 7 pulleys, 8 positive stops, 9 fixed blocks, 10 auricles with holes, 11 terraced fixed mounts.
The specific embodiment
As shown in Figure 1, the utility model comprises terraced fixed mount 11 and the inclined ladder frame 5 that is connected with terraced fixed mount 11, on inclined ladder frame 5, be set with stop device, described stop device comprise crank 2, with hinged connecting rod 3 of crank 2 one ends and the rocking bar 4 hinged with connecting rod 3 one ends; Described crank 2 is connected with inclined ladder frame 5 by auricle 10 with holes with rocking bar 4 and is hinged with auricle with holes 10, be provided with pulley 7 in described rocking bar 4 lower ends, on crank 2, be set with handle 1, handle (1) is welded on crank (2) and auricle with holes (10) link, pull handle 1 and can drive pulley 7 and move up and down, be set with positive stop 8 with connecting rod 3 links at described crank 2.Described stop device is symmetricly set on two inclined ladder framves (5).
When working stand is steadily placed, as shown in Figure 1,, two pulleys 7 of stop device do not play a supportive role though landing, and this moment, ladder supported by two fixed blocks 9 and two fixed feet 6, placed steadily.When working stand needs transfer location, as shown in Figure 2, only need depress handle 1, by crank 2 with connecting rod 3 drives rocking bar 4 under the effect of power and pulley 7 moves down, pulley 7 is landed, fixed feet 6 is lifted.At this moment, four wheels plays a supportive role, and ladder can be moved to desired location easily.After moving to reposition, only need handle 1 is upwards turned back, drive pulley 7 and move up, at this moment, fixed feet is put down and is landed, and stop device recovers back previous status.
When the center of crank 2 and connecting rod 3 in line the time, stop device is in " dead point " state, in real work, out of hand for preventing to make mechanism rush across " dead point " under the various uncertain factor effects, we are that crank 2 one ends fixedly install a positive stop 8 at driving link, stop operating when making crank 2 rotate to " dead point ", stop device is in the lock state.
The utility model working stand is to be the monolateral trapezoidal weld holder that meets at right angles that the tubing of 30mm is welded by diameter, evenly be provided with the pedal that highly is about 260mm on the hypotenuse, crank 2 is no more than 800mm with the pin joint height overhead of connecting rod 3, handle 1 peak height overhead is no more than 1600mm, and purpose is to be convenient for people to firmly.With respect to same working stand, the pin joint determining positions of connecting rod 3 and rocking bar 4 stop device rotate the size of required power.This distance from fixed block 9 is far away more, and power is more little, and the shared bulk of stop device is also big more; Otherwise distance is more little, and power is big more.Put extreme position when overlapping with center of gravity when this, 6 of fixed feet can not be lifted, and this device is ineffective.In the ordinary course of things, we are provided with the position of this pin joint in 1/2nd positions of working stand length.After the position of these two important pin joints had been arranged, we can calculate and be provided with the position of other pin joints according to motion theory.
The utility model is by increasing stop device, as long as pull handle 1, just can realize the conversion of pulley 7 and fixed feet 6, the quick conversion of steady placement and transfer location state when realizing ladder work, time saving and energy saving, be particularly useful for checking, maintenance of equipment etc. needs the frequent place of changing the position.
