Abstract
The invention discloses a kind of elevator counterweight structures, including shell and it is arranged in the intracorporal concrete block of shell, the inner walls are provided with memory alloy layer, heating wire is provided in the memory alloy layer, the connector being electrically connected with heating wire is provided on shell, the concrete block side wall is provided at least one groove, has the protrusion being clamped with groove when memory alloy layer is in room temperature in the corresponding position of groove, and when heating reaches more temperature, protrusion disappears.The elevator counterweight structure of the structure, on the one hand, it is convenient to carry, install and replace, and on the other hand, the recycling of shell is simply easy.
Description
Technical field
The present invention relates to elevator counterweight technical fields, and in particular to a kind of elevator counterweight structure.
Background technique
Elevator counterweight block, also known as elevator counterweight block.It is arranged in the counterweight system of elevator, for increasing counterweight system
Weight, to improve traction capacity, reduces traction machine power to reach the weight of balance carriage and fractional load.It is existing
Clump weight be typically all in 1 metal shell casting concrete be made.Although the clump weight that manufacture obtains in this way is made
Cause relatively low, and manufacturing process is also fairly simple.But still have some problems, the clump weight weight ratio after casting
It is heavier, typically in 30kg or more, carry, install it is relatively difficult.Furthermore it needs when car structure changes to counterweight system
In the case that clump weight in system carries out replacement reduction clump weight, when the weight of one piece of clump weight is not achieved in the weight of reduction,
One piece of slightly light clump weight of weight is then also needed replacing, so that the replacing construction of clump weight is long, replacement is complicated.
And existing clump weight is overall structure, when clump weight is scrapped, since concrete and metal shell closely bond together,
So that the recycling of metal shell is relatively difficult.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of elevator counterweight structures, on the one hand, carry, install and replace
Convenient, on the other hand, the recycling of shell is simply easy.
The present invention is solved the above problems by following technological means: a kind of elevator counterweight structure, including shell and setting exist
The intracorporal concrete block of shell, the inner walls are provided with memory alloy layer, heating wire, shell are provided in the memory alloy layer
The connector being electrically connected with heating wire is provided on body, the concrete block side wall is provided at least one groove, memory alloy layer
There is the protrusion being clamped with groove in the corresponding position of groove, protrusion disappears when heating reaches more temperature when in room temperature.
Further, the shell side is provided with the thread bush connecting with housing into rotation, and the shell other side is provided with and spiral shell
Line covers matched screw rod.
Further, push plate is provided in the shell, the push plate is connect by spring with housing bottom.
Beneficial effects of the present invention: elevator counterweight structure of the invention, including shell and setting are in the intracorporal concrete of shell
Block, the inner walls are provided with memory alloy layer, and heating wire is provided in the memory alloy layer, are provided on shell and electricity
The connector of heated filament electrical connection, the concrete block side wall is provided at least one groove, recessed when memory alloy layer is in room temperature
The corresponding position of slot has the protrusion being clamped with groove, and when heating reaches more temperature, protrusion disappears.The elevator of the structure is matched
Weight structure, on the one hand, it is convenient to carry, install and replace, and on the other hand, the recycling of shell is simply easy.
Detailed description of the invention
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
Below with reference to attached drawing, the present invention is described in detail, a kind of elevator counterweight structure, including shell as shown in Figure 1:
In the intracorporal concrete block 2 of shell, the inner walls are provided with memory alloy layer 3, set in the memory alloy layer for body 1 and setting
It is equipped with heating wire 4, the connector 5 being electrically connected with heating wire is provided on shell, the concrete block side wall is provided at least one
Groove 6 has the protrusion 7 being clamped with groove, when heating reaches more in the corresponding position of groove when memory alloy layer is in room temperature
Protrusion disappears when temperature.In use, heating by heating wire to memory alloy layer, memory alloy layer is made to reach more alternating temperature
Degree, facilitates and concrete block is put into shell, then stops heating memory alloy layer, makes formation and groove on memory alloy layer
The protrusion of clamping, realization concrete block and shell are bonded；When needing to remove concrete block, to memory alloy layer plus
Heat makes raised disappearance, concrete block can be made to skid off shell.In conclusion the elevator counterweight structure of the structure, using combined type
Structure, on the one hand, it is convenient to carry, install and replace, and on the other hand, the recycling of shell is simply easy.
As further improvement to above-mentioned technical proposal, the shell side is provided with the screw thread connecting with housing into rotation
Set 8, the shell other side is provided with and the matched screw rod 9 of thread bush.By the screw rod of the thread bush of a shell and another shell
It is threadedly coupled, the splicing of two counter weight constructions can be realized, to adapt to the use demand of different conditions.
As further improvement to above-mentioned technical proposal, push plate 10 is provided in the shell, the push plate passes through bullet
Spring 11 is connect with housing bottom.When dismantling concrete block, spring pushes push plate to move up, and then concrete block is ejected upwards,
Facilitate taking-up concrete block.
Finally, it is stated that the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although referring to compared with
Good embodiment describes the invention in detail, those skilled in the art should understand that, it can be to skill of the invention
Art scheme is modified or replaced equivalently, and without departing from the objective and range of technical solution of the present invention, should all be covered at this
In the scope of the claims of invention.
