The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of elevator safety component detection test stand
Trammer dedicated, the device for accepting the test stand surprisingly to land, can effective guarantee ground handling operator safety.
In order to solve the above-mentioned technical problem, the utility model provides the following technical solutions: a kind of elevator safety component detection
Test stand trammer dedicated a characterized by comprising cylinder base；At least two wheels are set to cylinder base close to the side of bottom position；
One support column can be arranged in cylinder base up or down；One lower supporting plate is set to the bottom of the support column, and cross-sectional area is big
In the outer diameter of cylinder base；Multiple springs link the Spring hanging rod being arranged on lower supporting plate and cylinder base outer wall；One catch bar is set to cylinder
Seat rear end and upwardly extend, top to ground distance be less than support column length.
Further, the side of the cylinder base is set there are two symmetrical wheel, and the catch bar is close to one end of the cylinder base
Equipped with the support rod for extending to ground.
Further, a fixing axle is horizontally set at the front end of the cylinder base, and two wheels are respectively arranged on fixed both ends of the shaft.
Further, a upper backup pad is set at the top of support column, and the cross-sectional area of upper backup pad is greater than the cross section of support column
Product.
Further, the lower supporting plate is equipped with links corresponding spring and hangs with U-loop corresponding above and below Spring hanging rod, spring
Bar and U-loop.
Further, the catch bar is equipped with proficiency shank far from one end of cylinder base.
Compared with prior art, the utility model beneficial effect achieved is:
When replacing the test safety tongs of test stand bottom, the cart is placed in elevator safety component detection test stand bottom,
Test stand can be effectively prevent to fall suddenly, play the role of protection to the personal safety of ground handling operator.
This cart structure is simple, flexible and convenient to use, links lower supporting plate and Spring hanging rod, support column decline using spring
When can play certain abirritation, reduce the impact force of lower supporting plate and ground.Meanwhile the upward out support column of test stand
When, support column automatically resets under the action of extension spring, i.e., without can be convenient in the state of support test stand mobile.
Detailed description of the invention
Attached drawing is used to provide a further understanding of the present invention, and constitutes part of specification, practical with this
Novel embodiment is used to explain the utility model together, does not constitute limitations of the present invention.In the accompanying drawings:
Fig. 1 is the structural schematic diagram of the utility model trammer dedicated；
Fig. 2 is the side view of the utility model trammer dedicated；
Fig. 3 is the front view of the utility model trammer dedicated.
Wherein, 10- support column；11- upper backup pad；13- lower supporting plate；14-U shape ring；20- cylinder base；21- Spring hanging rod；
30- spring；40- fixing axle；50- wheel；70- catch bar；71- handlebar；72- support rod.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1-3, the present embodiment provides a kind of elevator safety components to detect test stand trammer dedicated, including a cylinder base
20, support column 10, vehicle wheel component and catch bar 70.The cylinder base bottom is raised by vehicle wheel component support, is equipped among it up and down
The accommodating chamber of perforation, to accommodate the support column, the side of the cylinder base is equipped with Spring hanging rod 21.The support column 10 is arranged in
In cylinder base, top surface and ground set a upper backup pad 11 and lower supporting plate 13 respectively.The cross-sectional area of upper backup pad is greater than support
For the cross-sectional area of column preferably to accept the test stand surprisingly to land, the cross-sectional area of lower supporting plate is greater than the outer diameter of cylinder base, when
When support column declines, what lower supporting plate can be more stable is adjacent to ground, promotes the overall stability of cart.In addition, lower supporting plate
Upper surface is equipped with multiple U-loops 14, and U-loop is corresponding up and down with Spring hanging rod position and links corresponding Spring hanging rod by spring
And U-loop.It is acted on by the elastic reset of spring 30, in support column not contact test frame, lower supporting plate and ground keep one
Set a distance facilitates the transport of cart.In the present embodiment, the spring is two and the bilateral symmetry centered on cylinder base, is conducive to
Constitutional balance, in other embodiments, spring may be alternatively provided as other quantity.The catch bar 70 is set to the rear end of cylinder base and inclines
It extends obliquely upward, the distance of the catch bar upper end to ground is less than the length of support column.Proficiency shank 71 is set to catch bar
Top manipulates convenient for user.
Please refer to Fig. 1-3, in the present embodiment, the vehicle wheel component includes the fixing axle for being welded in the front end of the cylinder base
40, two wheels 50 are symmetrically disposed on fixed both ends of the shaft in favor of constitutional balance.The catch bar is close to one end of the cylinder base
Equipped with the support rod for extending perpendicularly to ground, using support rod and two wheels formed three-point supports play simultaneously it is quiet with ground
Rubbing action prevents cart from sliding.In other embodiments, vehicle wheel component can be arranged to other quantity according to the actual situation,
Such as it is arranged to the two parallel four wheel groups in front and back.
As shown in Figure 1-3, this cart is in use, its principle is: in elevator safety component detection test stand bottom replacement peace
Before full pincers, first the special handcart is placed in immediately below test stand, when hitting upper backup pad 11 when test stand accidental falling,
Support column decline is until lower supporting plate 13 is adjacent to ground, and since putting for support column 10 makes use, test stand will not further fall,
Casualties is avoided, spring is in tensional state at this time.When the upward out support column of test stand, support column is in extension spring
It automatically resets under effect.
Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
