Specific embodiment
Technical solution of the present invention is further non-limitingly described in detail below in conjunction with preferred embodiment and its attached drawing.
As shown in Figure 1, corresponding to a kind of electromagnetic brake mechanism of the medical bridge tower crane of preferred embodiment of the present invention, including leading
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 pass through shifting roller 5 along
Guide-track groove 1a is moved.
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 on the upper armature 7b and lower armature 7c of the upper and lower sides of pedestal 7a 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, upper and lower armature 7b, 7c are in the work of spring force
It is offseted respectively with upper and lower side wall 1aa, 1ab of guide-track groove 1a with lower stretching, so as to which mobile module 2 is 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.
For the brake weight of enhancing 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 mode of electromagnetic brake supporting rack 6 are as follows：It stops in electromagnetism
The strip hole 6a of twice vertical direction setting 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 and strip hole 6a between head of screw 8a and threaded portion 8c and match
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 respectively with upper and lower side wall 1aa, 1ab of guide-track groove 1a, electromagnetic brake 7 can
Position is adjusted in strip hole 6a, to adapt to the installation of guide rail 1 and electromagnetic brake 7 and scale error so that upper and lower friction plate
7d, 7e can be more closely bonded with upper and lower side wall 1aa, 1ab of guide-track groove 1a respectively, 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 and lower wall 1ab rubs, and influences to use, therefore is equipped with bulb plunger 7g, bulb plunger 7g in pedestal 7a lower surfaces
The bulb 7ga at top is contacted when lower armature 7c retracts with lower wall 1ab, so as to prevent lower friction plate 7e and lower wall 1ab from connecing
It touches.When mobile module 2 is pushed to move, bulb 7ga is rolled, and mobile module 2 can be pushed, and will not generate using the power of very little
Friction noise.
