Detailed Description

The invention is explained in detail below with reference to the figures and examples.

Example (b): as shown in fig. 1 to 8, a novel adjustable construction elevator, include well 15, car 12, hauler 5, to heavy 14, put quick-witted frame and reduction gear, put the quick-witted frame including putting quick-witted girder steel 1, it is equipped with channel-section steel subassembly 400 to put quick-witted girder steel 1 upper portion, hauler 5 installs on channel-section steel subassembly 400, channel-section steel subassembly 400 upper portion is equipped with platform subassembly 600, is equipped with cylinder 7 in platform subassembly 600 or on the floor in the door opening outside, and wire rope is connected to the cylinder, and one end of wire rope 9 is connected and is fixed on cylinder 7, and another connects car 12 through rope end stick 800 on channel-section steel subassembly 400, the upper portion of rope end stick 800 is equipped with rope end clamp 13.

The main machine of the elevator is a synchronous main machine, and the traction ratio is 2: 1. In this embodiment, there are 5 rollers and 5 corresponding wire ropes.

The elevator is additionally provided with a platform assembly 600 and a roller 7 on the basis that a telescopic assembly 2 and a push rod 3 for enabling the telescopic assembly 2 to be telescopic are arranged on one side of a machine placing steel beam 1 in a machine placing frame of the elevator with the prior patent number of 2019109563315, wherein the platform assembly 600 can be used for a worker to operate a platform and has the function of protecting a traction machine 5. The roller 7 is used for storing a steel wire rope 9, in the prior art, the steel wire rope 9 penetrates out from the traction machine 5 to two sides, one end of the steel wire rope is connected with the lift car 12, the other end of the steel wire rope is connected with the counterweight 14 through the guide wheel 440, in the patent, the steel wire rope 9 connected with the lift car 12 is upwards connected with the rope head rod 800, the rope head clamp 13 and the roller 7 through the top wheel 15, and the head of the steel wire rope 9 is fixed on the roller 7. The drum 7 is installed in the platform assembly 600 to be lifted up and down with the main frame when the height of the lifter is to be raised or lowered, and is installed on the floor outside the door opening, so that the load of the main frame is not increased. Rope end stick 800 in this patent is different from the rope end stick among the prior art, and rope end stick wire rope passes the taper sleeve among the prior art, because rope end stick integrated configuration can pin wire rope, can only change wire rope if under the condition that wire rope length needs the adjustment, causes the installation inconvenient, cost increase. In the patent, when the rotation stopping pin 840 is pulled out, the wire rope 9 can be adjusted by rotating the roller 850, and the rotation stopping pin 840 is inserted after the wire rope 9 is adjusted to fix the roller 850.

The working process of the elevator for lifting or lowering the height comprises the following steps: when the elevating height of the elevator is increased, the rope clamp 13 is loosened, the steel wire rope 9 is wound on the roller 850 by the rope head rod 800, and when the rotation stopping pin 840 is pulled out, the wire rope 9 wound on the drum 7 can be extended by the traction force of the traction machine or the manual force by adjusting the wire rope by rotating the roller 850, because the steel beam 1 of the machine placing is directly erected in the door opening and fixed through the bolts, the bolts are required to be loosened at the moment, the steel beam 1 of the machine placing enables the telescopic assembly 2 to be telescopic to a position suitable for a well through the push rod 3, and then is pulled and hung to a required height through the hoist, then the machine placing steel beam 1 enables the telescopic assembly 2 to extend and support on a plane surface where a top layer door opening of a hoistway is located through the push rod 3, the roller 850 of the rope head rod 800 is rotated until the steel wire rope 9 is tensioned, the rotation stopping pin 840 of the rope head rod 800 is inserted and fixed into the roller 850, and finally the steel wire rope 9 is clamped by the rope head clamp 13; if the lifting height of the lifter needs to be lowered, bolts on the steel beam 1 of the lifter are loosened, then the steel beam 1 of the lifter is pulled and hung to a required height through a hoist, then the steel beam 1 of the lifter enables the telescopic assembly 2 to extend and support on the plane surface where the top layer door opening of the hoistway is located through the push rod 3, then the rope end clamp 13 is loosened, the rotation stopping pin 840 is pulled out, the redundant steel wire rope 9 needs to be manually wound on the roller 7, the steel wire rope 9 is adjusted by the rotating roller 850 to be tensioned, then the rotation stopping pin 840 of the rope end rod 800 is inserted to fix the roller 850, and finally the steel wire rope 9 is clamped by the rope end clamp.

When the rollers 7 are located inside the platform assembly 600, the rollers 7 may move up or down along with the landing steel beam 1 and the platform assembly 600. When the drum 7 is mounted on the floor outside the door opening by means of the brackets 10: if the upper layer and the lower layer of the layer have no floor slab, the support 10 for installing the roller 7 is also lifted upwards or descended to the floor slab outside the door opening of the same layer of the steel beam 1 of the machine placing when the steel beam 1 of the machine placing is lifted upwards or descended; if the upper layer and the lower layer of the installation roller 7 are provided with the floor slabs, the steel beam 1 of the machine placing frame is punched on the upper layer floor slab and the lower layer floor slab when being lifted upwards or descended, the position of a bracket for installing the roller 7 is fixed, the steel wire rope 9 on the roller 7 is dismantled, and then the steel wire rope 9 is installed on the roller 7 through the holes on the upper layer floor slab and the lower layer floor slab; the support 10 for mounting the roller 7 can also be placed on the platform assembly 600 through the door opening, the support for mounting the roller 7 moves along with the girder 1 when the girder 1 of the machine is placed to move upwards or downwards, and the support for mounting the roller 7 is placed on the floor outside the door opening when the girder 1 of the machine is placed to move to a required height.
