Abstract
High-altitude operation platform extension mechanism device for opening, relate to physical construction technical field, comprise workplatform, described workplatform is provided with guardrail, more than one hold down groove is provided with in the bottom of described workplatform, the anchor shaft be connected on a parking brake line is inserted in described hold down groove, it is characterized in that: described parking brake line is successively through the first bent plate, one end of spring and the second bent plate and a U-shaped seat achieves a fixed connection, the other end of described U-shaped seat realizes being connected by bearing pin and one handle, described handle also realizes being connected by bearing pin with one handle bent plate, described handle bent plate is welded on described guardrail.Beneficial effect is: this device drives workplatform extendible portion to advance by parking brake, convenient and practical.
Description
Technical field
The present invention relates to physical construction technical field, be specifically related to a kind of convenient and practical high-altitude operation platform extension mechanism device for opening driving workplatform extendible portion to advance by parking brake.
Background technology
High-altitude operation platform extension mechanism overlaps above workplatform.Aerial platform scissor lifting heights, more than after more than 6-8m, needs platform front to work, at this moment just can open workplatform extendible portion.Workplatform extendible portion can expand the operating range of staff.What current workplatform extension mechanism was generally taked is tramp with one's feet to realize opening of workplatform extendible portion.
When foot-treadle, stretcher is lifted anchor shaft by lever principle, and workplatform just toward protracting, until anchor shaft is inserted in next hold down groove, can fix workplatform extendible portion.The shortcoming of this scheme is: after a pin steps on stretcher, and platform extension divides when performing fighting outward, and another pin also needs to go ahead, and causes the center of staff unstable, is not easy to go ahead.
Summary of the invention
The object of the present invention is to provide a kind of convenient and practical high-altitude operation platform extension mechanism device for opening driving workplatform extendible portion to advance by parking brake.
Technical matters solved by the invention realizes by the following technical solutions:
High-altitude operation platform extension mechanism device for opening, comprise workplatform, described workplatform is provided with guardrail, more than one hold down groove is provided with in the bottom of described workplatform, the anchor shaft be connected on a parking brake line is inserted in described hold down groove, it is characterized in that: described parking brake line is successively through the first bent plate, one end of spring and the second bent plate and a U-shaped seat achieves a fixed connection, the other end of described U-shaped seat realizes being connected by bearing pin and one handle, described handle also realizes being connected by bearing pin with one handle bent plate, described handle bent plate is welded on described guardrail.
Described first bent plate is welded on described guardrail.
Described second bent plate is welded on described first bent plate, forms a grasping part with described first bent plate.
Described spring is located in the grasping part of described first bent plate and described second bent plate formation.
Described first bent plate and described second bent plate are equipped with through hole.
Described anchor shaft is also placed through in described through hole.
Described anchor shaft is connected on described parking brake line through a pad.
Described pad is between described first bent plate and described spring.
The diameter of described pad is greater than the diameter of described through hole.
The beneficial effect that the present invention has is: this device drives workplatform extendible portion to advance by parking brake, convenient and practical.
Accompanying drawing explanation
Fig. 1 is the present invention: the integral structure schematic diagram of high-altitude operation platform extension mechanism device for opening;
Fig. 2 is the present invention: the partial exploded view between the first bent plate and the second bent plate.
Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
Embodiment: with reference to shown in Fig. 1-2, high-altitude operation platform extension mechanism device for opening, comprise workplatform 1, described workplatform 1 is provided with guardrail 2, more than one hold down groove 3 is provided with in the bottom of described workplatform 1, the anchor shaft 5 be connected on parking brake line 4 is inserted in described hold down groove 3, described parking brake line 4 is successively through the first bent plate 6, spring 7 and the second bent plate 8 achieve a fixed connection with one end of U-shaped seat 9, the other end of described U-shaped seat 9 realizes being connected with handle 10 by bearing pin, described handle 10 also realizes being connected by bearing pin with handle bent plate 11, described handle bent plate 11 is welded on described guardrail 2.
Described first bent plate 6 is welded on described guardrail 2.
Described second bent plate 8 is welded on described first bent plate 6, forms a grasping part with described first bent plate 6.
Described spring 7 is located in the grasping part of described first bent plate 6 and described second bent plate 8 formation.
Described first bent plate 6 and described second bent plate 8 are equipped with through hole 12.
Described anchor shaft 5 is also placed through in described through hole 12.
Described anchor shaft 5 passed a pad 13 and was connected on described parking brake line 4.
Described pad 13 is between described first bent plate 6 and described spring 7.
The diameter of described pad 13 is greater than the diameter of described through hole 12.
More than show and describe groundwork of the present invention and principal character and advantage of the present invention.The technical personnel of the industry should be understood; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
