Description
Technical field
The present invention relates to a kind of toeguard, particularly a kind of resistance to deformation elevator toe guard.
Background technology
Elevator toe guard is typically mounted on the bottom of bridge railway carriage or compartment sill, and it is to prevent lift car leveling from shifting to an earlier date before terminating that it, which is acted on,
When car sill is higher by landing sill after enabling or flat bed toe is injured because of shearing.But due to existing elevator toe guard stress
Intensity is relatively low, causes elevator toe guard that different degrees of deformation and bending occur after stress, so as to influence the guarantor of toeguard
Protect effect；And elevator cab needs continuous start and stop and speed change to move in lifting process, can also be caused in movement certain
Vibrations, toeguard needs is born vibrations and the pressure that elevator cab is brought for a long time, cause toeguard after long-term use can
, certain potential safety hazard be present in the problem of appearance loosens or dropped.Therefore, existing toeguard exist non-deformability it is weak, peace
The problem of full property difference.
The content of the invention
It is an object of the present invention to provide a kind of resistance to deformation elevator toe guard.It has that non-deformability is strong, and security is good
The characteristics of.
Technical scheme：A kind of resistance to deformation elevator toe guard, including support frame, the end of support frame is provided with U-shaped
Groove, support frame outside are connected with fixed plate through multiple strip holes, and dead plate upper end is provided with multiple suspension hooks, and suspension hook one end is through rectangular opening
Support frame is connected, spacing bracket is provided with the inside of fixed plate, spacing bracket upper end connection support frame, spacing bracket both sides, which are provided with, to be fixed
U-type groove bottom is close in positioning angle steel on the inside of fixed plate, positioning angle steel upper end；The fixed plate bottom is provided with dovetail groove, ladder
The stiffener plate of multiple plates that are connected is provided with shape groove.
In a kind of foregoing resistance to deformation elevator toe guard, the width ratio of the rectangular opening and suspension hook is 1.5:1.
In a kind of foregoing resistance to deformation elevator toe guard, the spacing bracket includes the limiting plate of V-arrangement, limiting plate both sides point
Not She You orthogonal first installing plate and the second installing plate, the first installing plate is connected plate, the second installing plate connection branch
Support.
Compared with prior art, the present invention can play position-limiting action by spacing bracket to fixed plate, avoid fixed plate
Occur bending after by side force or deform the problem of；Longitudinal direction can be played to fixed plate and is determined by positioning angle steel and U-type groove
The effect of position, can play a part of located lateral to fixed plate by suspension hook and rectangular opening, avoid fixed plate by external force
Or make fixed plate after long-term use being capable of stable connection junction build-up of pressure during vibrations.In addition, the present invention passes through fixation
Plate bottom dovetail groove can collect the chip and debris that elevator drops in lifting, ensure the clean safety of elevator hoistways；Pass through
Stiffener plate on dovetail groove can improve the intensity of fixed plate lower end, avoid debris from causing the deformation of dovetail groove when dropping.
So the present invention has the characteristics of non-deformability is strong, and security is good.

Embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples, but be not intended as to the present invention limit according to
According to.
Embodiment.A kind of resistance to deformation elevator toe guard, form as shown in Figure 1,2 and 3, including support frame 1, support frame 1
End is provided with U-type groove 101, and the outside of support frame 1 is connected with fixed plate 2 through multiple strip holes 102, and the upper end of fixed plate 2 is provided with multiple
Suspension hook 201, the one end of suspension hook 201 connect support frame 1 through rectangular opening 103, and the inner side of fixed plate 2 is provided with spacing bracket 3, spacing bracket 3
Upper end connects support frame 1, and the both sides of spacing bracket 3 are provided with the positioning angle steel 4 for being fixed on the inner side of fixed plate 2, and positioning angle steel 4 upper end is tight
Paste the bottom of U-type groove 101；The bottom of fixed plate 2 is provided with dovetail groove 202, and multiple plates 2 that are connected are provided with dovetail groove 202
Stiffener plate 203.
The width ratio of the rectangular opening 103 and suspension hook 201 is 1.5:1.
The spacing bracket 3 includes the limiting plate 301 of V-arrangement, and the both sides of limiting plate 301 are respectively equipped with orthogonal first peace
The installing plate 303 of loading board 302 and second, the first installing plate 302 are connected plate 2, the second installing plate 303 connection support frame 1.
The operation principle of the present invention：After support frame 1 is arranged on car sill bottom, the suspension hook 201 at the top of fixed plate 2 is detained
Enter in the rectangular opening 103 of support frame 1, suspension hook 201 will be close to the bottom of U-type groove 101 after buckling at the top of the positioning angle steel 4 in fixed plate 2
The cooperation of portion, suspension hook 201 and rectangular opening 103 can play a part of cross spacing to fixed plate 2, position angle steel 4 and support frame 1
Cooperation can play a part of longitudinal spacing while itself stress intensity of fixed plate 2 is strengthened to fixed plate 2, solid so as to reduce
The vibration amplitude of fixed board 2 at work；Bolt is arranged on the outside of U-type groove 101 by fixed plate 2 after positioning through strip hole 102, U-shaped
Groove 101 can increase support frame 1 structural strength of itself, and strip hole 102 can increase adjustment amplitude of the fixed plate 2 in longitudinal direction,
Ensure the stable installation of fixed plate 2；Respectively by the first installing plate 302 of spacing bracket 3 and the second installing plate after the installation of fixed plate 2
303 are arranged in fixed plate 2 and support frame 1, when fixed plate 2 is in stress, pressure that fixed plate 2 can be subject to by spacing bracket 3
Power passes to cage bottom through support frame 1, so as to improve the stress intensity of fixed plate 2, and can be with by the first installing plate 302
Fixed plate 2 and extraneous contact area are effectively increased, so as to reduce amplitude of deformation of the fixed plate 2 after stress, non-deformability
By force, security is good.The dovetail groove 202 of the bottom of fixed plate 2 can effectively collect the debris that passenger drops when passing through car sill
And chip, so as to keep the clean of the hoistway of elevator, stiffener plate 203 can strengthen the stress intensity of dovetail groove 202, avoid ladder
There is the situation for deforming or being broken after stress in shape groove 202.
