Specific implementation mode
Technical solutions of the utility model are made below in conjunction with preferred embodiment and its attached drawing further unrestricted detailed Explanation.
As shown in Figure 1, correspond to a kind of electromagnetic brake mechanism of the medical bridge tower crane of preferred embodiment of the utility model, packet Include guide rail 1, the moveable electromagnetic brake module 3 for being connected to the mobile module 2 of guide rail 1 and being installed on mobile module 2.
As shown in Figures 2 to 4, guide rail 1 is preferably section aluminum guide rail, and both sides are symmetrically arranged with guide-track groove 1a, guide-track groove 1a includes the upper side wall 1aa being oppositely arranged and lower wall 1ab.Mobile module 2 include the mobility framework 4 that takes the shape of the letter U of section and Four shifting rollers 5 being symmetricly set in mobility framework 4.Shifting roller 5 is fastened in guide-track groove 1a, with guide-track groove 1a's Upper and lower side wall 1aa, 1ab cooperation.Mobile module 2 is connected to by shifting roller 5 on guide rail 1, and by shifting roller 5 along Guide-track groove 1a movements.
Installing port 4a is symmetrically offered on the two sides of mobility framework 4, electromagnetic brake module 3 is installed on the installing port In 4a.Electromagnetic brake module 3 includes electromagnetic brake supporting rack 6 and electromagnetic brake 7.Electromagnetic brake supporting rack 6 is connected by screw In in mobility framework 4, electromagnetic brake 7 is installed on by shaft shoulder screw 8 on electromagnetic brake supporting rack 6, and electromagnetic brake 7 be located at lead In track slot 1a.
As shown in Figure 5 to Figure 6, electromagnetic brake 7 includes pedestal 7a, the coil (not shown) being arranged in pedestal 7a, difference Be arranged the upper and lower sides pedestal 7a upper armature 7b and lower armature 7c and be arranged in pedestal and both ends with respectively with upper and lower rank Several compressed spring (not shown) that iron 7b, 7c offset.When coil is not powered on, the work of upper and lower armature 7b, 7c in spring force It is offseted respectively with upper and lower side wall 1aa, 1ab of guide-track groove 1a with lower stretching, to which mobile module 2 to be fixed on guide rail 1.When When coil is powered, suction will be generated to upper and lower armature 7b, 7c so that upper and lower armature 7b, 7c overcome spring force to bounce back, at this point, Mobile module 2 can be pushed to be moved on guide rail 1.
To enhance the brake weight of electromagnetic brake 7 and guide rail 1, upper friction plate 7d is respectively arranged on upper and lower armature 7b, 7c With lower friction plate 7e.
As shown in Fig. 7 to Fig. 8, electromagnetic brake 7 and the specific connection type of electromagnetic brake supporting rack 6 are as follows:It stops in electromagnetism The strip hole 6a that the setting of twice vertical direction is offered on vehicle supporting rack 6, opens up that there are two the spiral shells for installation on electromagnetic brake 7 Pit 7f, shaft shoulder screw 8 are provided with the shaft shoulder portion 8b, shaft shoulder portion 8b between head of screw 8a and threaded portion 8c and match with strip hole 6a It closes.Shaft shoulder screw 8 is threadedly coupled across strip hole 6a with threaded hole 7f, and after connection, electromagnetic brake 7 can pass through shaft shoulder screw 8 It is free to slide along strip hole 6a.The advantage of this structure is:It is relatively low to the dimension precision requirement of guide rail 1 and electromagnetic brake 7. When upper and lower armature 7b, 7c of electromagnetic brake 7 offset with upper and lower side wall 1aa, 1ab of guide-track groove 1a respectively, electromagnetic brake 7 can Position is adjusted in strip hole 6a, to adapt to installation and the scale error of guide rail 1 and electromagnetic brake 7 so that upper and lower friction plate 7d, 7e can respectively with upper and lower side wall 1aa, 1ab of guide-track groove 1a are closer is bonded, improve the reliability of brake and steady Property.
As shown in figs. 6 and 9, after electromagnetic brake 7 moves down under the effect of gravity after being powered in order to avoid coil, cause under it Friction plate 7e rubs with lower wall 1ab, influences to use, therefore is equipped with bulb plunger 7g, bulb plunger 7g in the lower surfaces pedestal 7a The bulb 7ga at top is contacted when lower armature 7c retracts with lower wall 1ab, to prevent lower friction plate 7e and lower wall 1ab from connecing It touches.When pushing mobile module 2 to move, bulb 7ga is rolled, and can push mobile module 2 using the power of very little, and not will produce Friction noise.
The electromagnetic brake mechanism of the medical bridge tower crane of the utility model includes at least following advantages:
1. the medical bridge tower crane of the utility model makes traditional air bag brake into electromagnetic brake, fast response time, using can It leans on, is hardly damaged, the service life is longer, and without using compressed air-driven, simple in structure, small;
2. the electromagnetic brake mechanism of the utility model is provided with upper and lower armature, it can offset with guide-track groove and play braking Effect, braking effect are more preferable than the effect of unilateral armature;
3. the electromagnetic brake of the utility model is flexibly connected with electromagnetic brake supporting rack, to the size of guide rail and electromagnetic brake And installation accuracy requirement is low, use is more convenient, reliable;
4. mobile module moves, for friction plate not with guide rail contact, friction noise is small.
It should be pointed out that above-mentioned preferred embodiment is only to illustrate the technical concepts and features of the utility model, purpose It is the content for allowing person skilled in the art that can understand the utility model and implements according to this, this reality can not be limited with this With novel protection domain.It is all according to equivalent change or modification made by the spirit of the present invention essence, should all cover in this reality Within novel protection domain.
