The utility model discloses design the upper and lower casing of the joint portion of traditional tower machine stopper into spacing draw -in groove and spacing stair structure respectively, on the rubber packing ring can overlap a step of limiting, spacing draw -in groove was detained and is put on spacing step, has improved the efficiency and the quality of installation, has reduced because of installing the circumstances that the packing ring was abandoned in inconvenience.
Description
Technical field
This utility model is related to architectural engineering tower crane field, and in particular to a kind of tower crane stop upper-lower casing joint portion.
Background technology
Tower crane stop is a kind of safety for preventing jack machinism generation collision or restriction from running within the specific limits.
During tower crane stop maintenance and installation, existing tower crane stop upper-lower casing joint portion is groove shapes, installs inconvenient,
If it is improper slightly to control, seal washer can be caused to install not in place, or even the problem for coming off；Affect making for tower crane stop
With such as some tower crane stops are safeguarded when installing and using, and because of the bad installation of sealing rubber pad, cause attendant to abandon rubber
Sealing gasket, now affect tower crane stop installs and uses effect, while affecting service life and the sale of tower crane stop.Cause
This, the maintenance installation hidden danger for eliminating tower crane stop has great practical significance and economic implications.
At present, tower crane stop upper-lower casing joint portion is installed by the way of groove and special-shaped rubber washer.Consider
Cost Problems, upper-lower casing generally uses identical mould to produce.And there is following defect using this mould：1st, assembling effect
Rate is low；2nd, safeguard and inconvenience is installed, operator easily abandon special-shaped rubber washer, cause without buffering effect；3rd, special-shaped rubber
Packing ring is in the presence of a harsh environment using easy aging deformation, and it is unreliable to install.In view of this, a kind of preferable tower crane limit how is designed
Position device upper-lower casing joint portion, is the problem of insider's urgent need to resolve to solve the above problems.
The content of the invention
The purpose of this utility model is to provide a kind of tower crane stop upper-lower casing joint portion, and this joint portion can improve group
Dress efficiency, is easy to the installation of rubber washer, and convenient during maintenance etc. is installed, reliable.
The technical solution of the utility model：A kind of tower crane stop upper-lower casing joint portion, including upper shell, under upper shell
Side is correspondingly provided with lower house, and upper shell lower end is provided with spacing draw-in groove, and lower house upper end is provided with limited step, the interior length of spacing draw-in groove
It is wide to coordinate with limited step foreign minister broad gap.
Aforesaid tower crane stop upper-lower casing joint portion, between the upper shell and lower house rubber washer is provided with.
Compared with prior art, this utility model by the upper-lower casing of the joint portion of traditional tower crane stop separately design for
Spacing draw-in groove and limited step structure, rubber washer can be arranged on limited step, and spacing draw-in groove button is placed on limited step, improved
The efficiency installed and quality, reduce situation about abandoning on packing ring because installing inconvenience.

Fig. 2 is A-A faces sectional view in Fig. 1；
Fig. 3 is zoomed-in view at I；
Fig. 4 is prior art construction schematic diagram；
Fig. 5 is the zoomed-in view at B.
Labelling in accompanying drawing for：1- lower houses, 2- upper shells, 3 rubber washers, the spacing draw-in grooves of 4-, 5- limited steps.
Specific embodiment
This utility model is further described with reference to the accompanying drawings and examples, but is not intended as to this utility model
The foundation of restriction.
Embodiment.A kind of tower crane stop upper-lower casing joint portion, its structure is as shown in figure 1, including upper shell 2, upper casing
The lower section of body 2 is correspondingly provided with lower house 1, and the lower end of upper shell 2 is provided with spacing draw-in groove 4, and the upper end of lower house 1 is provided with limited step 5, spacing
The interior length and width of draw-in groove 4 coordinate with the foreign minister's broad gap of limited step 5.
Rubber washer 3 is provided between the upper shell 2 and lower house 1.
This utility model is a kind of tower crane stop upper-lower casing joint portion, and the lower end of upper shell 2 is designed as limited step 4 and ties
Structure, lower house 1 is designed as the structure of spacing draw-in groove 5, at the joint portion that both are constituted, forms the structure being mutually clamped.During installation,
Rubber washer 3 is first set on the bulge-structure of lower house 1, then the button of upper shell 2 is placed on both, and installation process is convenient can
Lean on, improve the efficiency of installation.Rubber washer 3 plays a part of buffering, it is to avoid rigid contact is to stop between upper-lower casing
Infringement, extend service life.
