Abstract
The utility model provides a construction hoist power assembly and belongs to the technical field of machines, and the construction hoist power assembly is used for solving the problem that a ventilation hood in an existing construction hoist power assembly is purchased independently and installed inconveniently. The construction hoist power assembly comprises a worm gear case, a motor and a brake, wherein the worm gear case comprises a worm gear and a worm; the worm gear case and the brake are installed at both ends of the motor respectively; and the worm is connected with the output shaft of the motor. The construction hoist power assembly is characterized in that an end cover is installed on the other end of the worm gear case and a ventilation hood formed integrally with the end cover; and a heat radiating device is installed in the end cover. The construction hoist power assembly provided by the utility model has the advantages that the ventilation hood is simple in structure and is formed integrally with the end cover, so that additional purchasing and installation are unnecessary.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of building hoist dynamic assembly.
Background technology
General main worm case, motor and the drg of comprising of existing building hoist dynamic assembly; Worm case and drg are separately positioned on the two ends of motor; Worm screw in the worm case is coaxial interlock with the output shaft of motor, and the other end of worm screw is provided with heat abstractor, distributes and guarantees that worm gear, worm screw can normal operation thereby heat abstractor is used for heat with worm case; Heat abstractor is with the end cap protection outward; End cap is connected on the worm case casing, and the ventilating hood that is used for ventilation and heat is installed on the end cap, and the problem of existence is the ventilating hood purchase and installs cumbersome.
Summary of the invention
The purpose of the utility model is to have the problems referred to above to existing technology, is made of one piece and need not to buy in addition and the building hoist dynamic assembly of installation ventilating hood thereby proposed a kind of ventilating hood and end cap.
The purpose of the utility model can realize through following technical proposal: a kind of building hoist dynamic assembly; Comprise worm case, motor and drg; Worm case comprises worm gear and worm screw, and worm case and drg are installed in the two ends of motor respectively, and described worm screw is connected with the output shaft of motor; It is characterized in that: be equipped with on the other end of described worm case end cap and with the integrated ventilating hood of end cap, heat abstractor is installed in the end cap.
In above-mentioned a kind of building hoist dynamic assembly, described heat abstractor comprises with worm screw bonded assembly main shaft and is connected in several fan blades on the main shaft.
Compared with prior art; The end cap that is used to protect heat abstractor in this building hoist dynamic assembly and the ventilating hood that is used for ventilation and heat are formed in one, and time processing forms; When production and processing, do not need on end cap, to open earlier a through hole, go to buy ventilating hood then and install again, simple in structure; Processing, easy for installation, and intensity is better.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure, 1, worm case; 2, motor; 3, drg; 4, end cap; 5, ventilating hood.
The specific embodiment
Below be the specific embodiment of the utility model and combine accompanying drawing, the technical scheme of the utility model is done further to describe, but the utility model is not limited to these embodiment.
As shown in Figure 1; This building hoist dynamic assembly comprises worm case 1, motor 2 and drg 3; Worm case 1 comprises worm gear and worm screw, and worm case 1 and drg 3 are installed in the two ends of motor 2 respectively, and worm screw is connected with the output shaft of motor 2; Be equipped with on the other end of worm case 1 end cap 4 and with end cap 4 integrated ventilating hoods 5, in the end cap 4 heat abstractor is installed.
Heat abstractor comprises with worm screw bonded assembly main shaft and is connected in a plurality of fan blades on the main shaft.
This building hoist dynamic assembly is when work; Motor 2 work drive worm screw work; Worm screw drives worm gear work on the one hand; The main shaft that drives on the other hand on the heat abstractor rotates, and main shaft rotates and driven the fan blade rotation, produces air-flow and takes the heat in the worm case 1 out of the external world through the breather port on the ventilating hood 5.The end cap 4 that is used to protect heat abstractor in this building hoist dynamic assembly and the ventilating hood 5 that is used for ventilation and heat are formed in one, and time processing forms, and is simple in structure, processing, easy for installation, and also intensity is high, long service life.
Specific embodiment described herein only is that the utility model spirit is made casehistory.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
Although this paper has used terms such as worm case 1, motor 2, drg 3, end cap 4, ventilating hood 5 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain the essence of the utility model more easily; It all is contrary with the utility model spirit being construed to any additional restriction to them.
