Abstract
The utility model provides a locking and fixing device for the start end of rubber sheathed cables. The utility model is composed of a frame part, a winding drum part arranged in the frame, a pressure plate compressed on the cable wound on the winding drum, and a rotary plain shaft. The locking and fixing device can overcome the defect that the common used ' omega '-shaped lock ring can damage the cable, and can cause the service life of the cable to be increased by more than ten times. The locking and fixing device is particularly suitable for matching with cable receiving and releasing devices of a clockwork spring type, a moment motor type, a hydraulic coupling type, a counterweight type, etc.
Description
The utility model relates to cable system, particularly rubber sleeve cable initiating terminal locking and fixing device.
The motor service cable of crane that carries out running job on rail is with the crane traveling.The super top of this cable is locked.Conventional locking and fixing device be adopt that two block plates make "
" shape ring, be pressed in cable initiating terminal two places, with screw with this "
" shape is encircled and cable is fastened on a certain fixture, reaches the purpose of locking.When crane locomotive starting traveling, the cable R-T unit on the crane locomotive tear power cable cause unexpected shake make first locking "
" shape ring is subjected to impact tension."
" edge of shape ring just blocks the local crust of voltage cable.After tearing repeatedly, blocking pressure, the cable sheath at this card pressure place is just leaked by mill and causes breakage, and along with the expansion gradually of breakage and deeply, the cable internal insulating layer is also destroyed thereupon gradually, causes short circuit or ground fault at last, and therefore cable is scrapped.Actual count is the result show, adopting φ 50mm rubber sleeve cable average life of this locking only is 3～4 months, causes the economic loss of units up to ten thousand every year.
The purpose of this utility model provides a kind of new type rubber cover cable initiating terminal locking and fixing device, with a cover reel system, is subjected to force direction by changing repeatedly, cuts down starting-impact power, raising cable useful life.
According to the super top of rubber sleeve cable of the present utility model locking and fixing device, constitute by four parts, i.e. Zhuan Zhi frame part, the reel part of device, cable pressing plate part and rotation axis part.
According to device frame part of the present utility model, by two block frame fixed base plates, four spill steel stiles, a block frame top board is formed.With anchor bolt fixed base plate is fixed on the ground; Two spill steel vertical frames are one group, and concave surface is opposing, and an end is vertically welded in respectively on the base plate, form "
" the shape structural framing, concordant welding one block plate of its end face at this steel plate loam cake upper frame pressing plate, links together these two groups of plates with bolt and nut.
According to reel of the present utility model part by a pipe (spool body), be welded on the spill steel part at these pipe two ends, cable compaction pressure value is regulated bolt and rubber blanket is formed, reel (pipe) is erected in the described framework, the spill steel part is welded on the pipe two ends, the slope mouth is opened in its lower end, outside, and force value is regulated bolt and is vertically welded in pipe end face two ends, with a rubber blanket pipe is wrapped up.The rubber sleeve cable just is wrapped on this rubber blanket.
Be pressed in cable plate for forcing on the cable by one and the rubber blanket between this plate for forcing and the cable is formed according to cable plate for forcing of the present utility model part.
According to rotation axis of the present utility model part by be through each "
" axis in the middle of the shape framework and hold-down nut thereof and split pin form.
The rubber sleeve cable that is locked with the utility model under the effect of crane starting power, can change repeatedly and is subjected to force direction, can utilize the elastic force of rubber sleeve itself and prolongs the impact force action time and weaken impulsive force gradually; Cable core and crust bear tension simultaneously, have prolonged the friction length between cable sheath and locking device, can adjust friction pressure automatically, and realize movable connection, thereby reach locking cable, improve the cable purpose in useful life.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is the elevational cross-sectional view of locking and fixing device of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the end view of Fig. 1.
As Fig. 1, Fig. 2, shown in Figure 3, locking and fixing device of the present utility model is made up of frame part, reel part, cable pressing plate part and rotation axis.
As shown in the figure, frame part is made up of identical two parts, and each part all has one to be fixed on base plate (1) on the ground, two spill stiles (3) that concave surface is opposing with fang bolt, the one end is vertically welded on the chassis base (1), thereby form "
" the shape framework, concordant welding steel (5) on its end face, establish above the steel plate (5) width and "
" the identical pressing plate (7) in shape frame upper end, with bolt-nut (6) concordant steel plate (5) and pressing plate (7) are linked together, form complete frame part.
Reel part by the pipe in framework (9), be welded on the spill steel part (10) at these pipe two ends, slope mouth (11) is opened in the lower end in this spill steel part (10) outside, the upright opening (4) of (3) two orthogonal center line intersection points of its interstitial hole (12) and spill stile is coaxial relative, size is identical, so that this reel is partly set up on the framework.Each vertical welding connects cable pressure value adjusting bolt (13) outside this pipe (9) two ends, this regulates bolt surface and is with gum sleeve (14), with a rubber skin (15) outer surface of whole pipe (9) is wrapped, rubber sleeve power cable (22) promptly is wrapped on this rubber skin (15).
Cable plate for forcing part of the present utility model is provided with rubber blanket (18) by the cable plate for forcing (16) of a compressing on power cable (22) between plate for forcing (16) and the cable (22), and force value is regulated bolt (13) and passed this plate for forcing two ends.
Rotation axis part of the present utility model is made up of the locking split pin (21) that is located at the middle axis (19) of framework, the nut (20) that is used for fixing this axis, this nut.
When using cable locking and fixing device of the present utility model, at first four holding screws on the pressing plate (7) are backed out, one in two axises (19) is taken out from upright opening (4), the axis that reel (9) is not taken out with another root serves as to lift on axially, and the fastening cable (22) of needs is wrapped on the reel (9) that is surrounded by rubber blanket (15).Cable plate for forcing (16) is adjusted screw (13) by cable compressing amount be pressed onto on the cable that has wound, and rubber blanket (18) is placed between cable and the plate for forcing.Adjust screw (13) plate for forcing (16) is adjusted to suitable degree to the compressing amount of cable (22).The cable that twined, the reel (9) of adjusting the compressing amount are rotated back into "
" in the frame, that root axis (19) that takes off when beginning cable is installed is first-class again, refills top board (7).
According to the utility model, under certain conditions, for example when indoor use, also can not establish the pressing plate (7) on the framework, with the simplified structure structure, simplify procedures.
According to device of the present utility model, can improve tens times of useful lifes of the open air of on rail linear directional operation, indoor crane power rubber sleeve cable, improve equipment operation rate, be particularly suitable for and " spring formula ", " torque motor formula ", " Vulcan coupling formula ", " Weight type ", " spring friction disk type ", the supporting use of " magnetic force friction disk type " folding and unfolding cable unit, respond well.
