Abstract
The invention discloses a pantograph structure of a rotary kiln power supply sliding ring. Extension springs (2) are connected with two connecting rods (3), the left end and the right end of each connecting rod (3) are respectively connected with a left steel pipe (6) and a right steel pipe (1) through a pin shaft (4) and a cotter pin (5), the upper end and the lower end of the left steel pipe (6) are inserted in an upper support (8), the upper end of the right steel pipe (1) is connected with a compression spring (11) and a small base plate (10) in a sliding block part (13) in a sleeved mode, and the sliding block part (13) and a sliding ring part (14) are connected. All preceding parts are of a bilateral symmetry structure. A base plate (7) is arranged between the lower end of the left steel pipe (6) and a lower support (9). An insulating body (12) is sleeved in the lower support (9), and the lower support (9) is connected with the upper support (8) through bolts (15). The pantograph structure enables the extension springs to be fixed reliably, and therefore contact stability of the sliding block and the sliding ring is improved.
Description
Technical field
The present invention relates to the pantograph of a kind of rotary kiln for electric slip ring.
Background technology
Usually all need in the posterior segment of carbon element rotary kiln Secondary Air and tertiary air device are installed, be used for supplementing appropriate air in kiln body, make the volatile substance of overflowing in material be able to Thorough combustion.The power supply of the air blast two, in tertiary air device is provided by power supply slip-ring device.Because kiln body rotates, two, tertiary air device also rotates thereupon, so be also rotate with kiln body for electric slip ring.Existing for electric slip ring and pantograph structure, there is the loose contact with the rotation of kiln body, cause the phenomenon of power supply instability, the problem of interruption of power supply even occurs, affects the normal operation of carbon element rotary kiln.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of rotary kiln for the pantograph structure of electric slip ring, the loose contact with rotating with kiln body of overcoming that prior art exists, causes the deficiencies such as power supply instability.
The present invention is by the following technical solutions: extension spring is connected on two connecting rods, and the left and right end of connecting rod is respectively by bearing pin, split pin and left steel pipe, right fastener for connection, and the upper and lower end of left steel pipe is inserted in upper bracket; Compress Spring in the upper end of right steel pipe and slider part and small raft socket-connect, and slider part is connected with slide ring portion; Described take upper-part as bilateral symmetry; Backing plate is provided with between the lower end and undersetting of left steel pipe; Insulator is enclosed within undersetting, and undersetting is connected with upper bracket.
Undersetting and upper bracket are bolted.
A backing plate is set in A steel pipe lower end, makes it drop on undersetting, have fixing effect, increase overall stability.Connecting rod connects with both sides steel pipe the structure adopting bearing pin to add split pin.Be flexible in working order due to extension spring and slide, to connecting rod and steel pipe connect require firm.Adopt bearing pin to add the structure of split pin, improve the stability that slide block contacts with slip ring, also ensure that the reliable fixation of extension spring.
The present invention adopts above structure, can ensure the reliable fixing of extension spring, thus the stability that raising slide block contacts with slip ring, guarantee that normal table is powered, carbon element rotary kiln is normally run.

Fig. 1 is structural representation of the present invention;
Fig. 2 is A-A sectional view, enlarged drawing in Fig. 1;
Fig. 3 is B-B sectional view, enlarged drawing in Fig. 1.
Detailed description of the invention
Embodiments of the invention: the structure of pantograph is as shown in accompanying drawing 1,2,3, and it is made up of right steel pipe 1, extension spring 2, connecting rod 3, bearing pin 4, split pin 5, left steel pipe 6, backing plate 7, upper bracket 8, undersetting 9, small raft 10, Compress Spring 11, insulator 12, slider part 13, slide ring portion 14 and connecting bolt 15.Extension spring 2 is connected on two connecting rods 3, and the left and right end of connecting rod 3 is connected with left steel pipe 6, right steel pipe 1 respectively by bearing pin 4, split pin 5, and the upper and lower end of left steel pipe 6 is inserted in upper bracket 8; Compress Spring 11 in the upper end of right steel pipe 1 and slider part 13 and small raft 10 socket-connect, and slider part 13 is connected with slide ring portion 14; Described take upper-part as bilateral symmetry (signal see Fig. 1); Backing plate 7 is provided with between the lower end and undersetting 9 of left steel pipe 6; Insulator 12 is enclosed within undersetting 9, and undersetting 9 is connected with upper bracket 8.
Undersetting 9 is connected by bolt 15 with upper bracket 8.
Claims (2)
1. the pantograph structure of a rotary kiln confession electric slip ring, it is characterized in that: extension spring (2) is connected on two connecting rods (3), the left and right end of connecting rod (3) is connected with left steel pipe (6), right steel pipe (1) respectively by bearing pin (4), split pin (5), and the upper and lower end of left steel pipe (6) is inserted in upper bracket (8); Compress Spring (11) in the upper end of right steel pipe (1) and slider part (13) and small raft (10) socket-connect, and slider part (13) is connected with slide ring portion (14); Described take upper-part as bilateral symmetry; Backing plate (7) is provided with between the lower end of left steel pipe (6) and undersetting (9); Insulator (12) is enclosed within undersetting (9), and undersetting (9) is connected with upper bracket (8).
