Description
Technical Field
The utility model relates to an elevator installation is with heavily protector.
Background
The general task of elevator field installation is heavy time limit tightly, therefore prior art adopts no scaffold frame mounting process mostly when the on-the-spot installation elevator, does not have the heavy guide rail of counter weight to the heavy frame when no scaffold frame installation and leads, takes place the incident easily when the installation.
Specifically, the old installation process in the prior art has the following defects:
1) the no scaffold frame installation counter weight does not have the guide rail to carry out the guide effect, and along with the car goes upward in the installation, the counter weight is down, if there is the barrier (reinforcing bar head, steel pipe etc.) in meeting the elevator well, will produce unpredictable irregular rotation to the frame of weighing. The counterweight iron is easy to throw out of the counterweight frame and hit personnel in the hoistway to be constructed on the lift car. This is a very dangerous operating mode for which some elevator companies prohibit scaffold-free construction. But the construction without the scaffold can greatly shorten the construction period and save the construction cost for setting up the scaffold in the construction. It is difficult for many elevator installation companies to abandon scaffold-free construction.
2) When no scaffold is constructed, the counterweight frame slides downwards along the wall of the elevator shaft, so that sundries on the wall of the elevator shaft are easy to scrape and rub down to directly fall on the body of constructors below, and the constructors are easy to hurt and equipment is easy to damage.
SUMMERY OF THE UTILITY MODEL
The utility model provides an elevator installation is with heavily protector, its purpose aims at overcoming the above-mentioned not enough that prior art exists, realizes effectively taking precautions against in no frame hand frame installation elevator to the pouring weight and drops, avoids rubbing the foreign matter that drops to the heavy framves, improves the construction security.
The technical solution of the utility model is as follows: the utility model provides an elevator installation is with heavily protector, its structure includes to heavy guide rail mounting, flexible guide rail and upper end mounting, wherein both sides are installed and are equipped with respectively to heavy guide rail mounting on the first row of well bottom to heavy guide rail, and the heavy guide rail mounting is connected to flexible guide rail bottom, and both sides flexible guide rail top is connected both sides respectively and is installed at well upper end or computer lab bottom upper end mounting, is equipped with guider on the flexible guide rail of both sides respectively relatively, connects between the guider of both sides to heavily putting up.
Preferably, the flexible guide rail is also provided with a locking mechanism.
The utility model has the advantages that: structural design is effective reasonable, compares traditional scaffold free elevator installation, can effectively take precautions against the pouring weight and get rid of, has avoided cutting to pieces to the heavy rack and rubs the foreign matter that drops, and construction safety nature can improve about 70%, and construction equipment repeatedly usable has reduced a large amount of manpowers and material cost input.
Drawings
Fig. 1 is the utility model discloses elevator installation is with to heavy protector's schematic structure view.
In the figure, 1 is a counterweight guide rail, 2 is a counterweight guide rail fixing piece, 3 is a flexible guide rail, 4 is a guide device, 5 is a counterweight frame, 6 is an upper end fixing piece, A is a hoistway bottom end, and B is a hoistway upper end or a machine room.
Detailed Description
The present invention will be described in further detail with reference to examples and embodiments.
As shown in fig. 1, a heavy protector is used in elevator installation, its structure includes to heavy guide rail mounting 2, flexible guide rail 3 and upper end mounting 6, wherein both sides are installed and are equipped with respectively to heavy guide rail mounting 2 on the first heavy guide rail 1 of well bottom A, 3 bottom connections of flexible guide rail are to heavy guide rail mounting 2, 3 tops of flexible guide rail of both sides are connected both sides respectively and are installed at well upper end or computer lab B bottom upper end mounting 6, be equipped with guider 4 on the flexible guide rail 3 of both sides respectively relatively, connect counterweight frame 5 between the guider 4 of both sides.
And the flexible guide rail 3 is also provided with a locking mechanism.
According to the above structure, when the device is installed,
1) the counterweight guide rail fixing part 2 is fixed with the first row of counterweight guide rails 1 at the bottom end A of the hoistway after installation;
2) fixed with the top end of the well or the upper end fixing piece 6 of the machine room B;
3) laying a flexible guide rail 3 (flexible guide device) according to the required guide rail distance in construction;
4) one end of the flexible guide rail 3 is connected with the counterweight guide rail fixing part 2, and the other end of the flexible guide rail is connected with the fixing part 6 at the upper end of the hoistway;
5) the flexible guide rail 3 is tightened and locked by a locking device;
6) the guide 4 is connected to the counterweight housing 5.
During locking, certain prestress is applied to the flexible guide rails 3, the counterweight frame 5 is kept to operate between the two rows of flexible guide rails 3 all the time, the counterweight frame is not scraped against the wall of a well, and disordered movement of the counterweight frame 5 is avoided.
When in construction, the steel pipe is put into operation,
1) the heavy frame 5 is restrained and can only operate in a limited range, and the disordered motion of the heavy frame 5 is changed into regular motion. Effectively avoid having the barrier to cause the action of endangering installer because of having throwing away of pouring weight in the well.
2) The movement of the counterweight frame 5 keeps a corresponding distance with the well wall, thereby ensuring the risk of foreign matter falling caused by rubbing the counterweight frame against the well wall.
3) The field installation is relatively simple and easy, and only upper end fixing is needed, and the guide device is fixed with the counterweight housing through locking of the locking element.
All the above components are prior art, and those skilled in the art can use any model and existing design that can implement their corresponding functions.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and improvements can be made without departing from the inventive concept, and all of them belong to the protection scope of the present invention.
