Description
Technical field
The utility model relates to a kind of suspension bracket, particularly a kind of industrial pipeline that is used for industries such as electric power, chemical industry or equipment and the groove guiding type constant-force spring hanger that occasions such as thermal walking and load is invariable need be arranged at vertical direction.
Background technique
At present, in industries such as electric power, chemical industry, often use suspension bracket fixing lifting industrial pipeline or equipment.Existing hanger structure is support to be arranged and be installed in the swing mechanism on the support through main shaft; Swing mechanism comprises two parallel rotor plates; Being positioned at a side of main shaft and the upper end of load bolt on the rotor plate is rotationally connected; The opposite side that is positioned at main shaft on the rotor plate has connecting plate, on connecting plate, is provided with the adjustment bolt, and the adjustment bolt is rotationally connected between two rotor plates and on inner end and the arm-tie.In the lower end of support front cover is arranged and be provided with upper and lower to guide cylinder; The lower end of arm-tie is equipped with the guide pad that matches with guide cylinder; The upper end of guide pad and stay-bolt joins; The lower end of stay-bolt is connected to pressing plate, between pressing plate and front cover, is provided with the spring that is enclosed within the stay-bolt outside, and there is the cylindrical shell that joins with front cover in the outside of spring.This device is fixed on the foundation frame through the top board of support top; The lower end of load bolt is connected with the lifted weight thing through the degree of tightness nut; Stay-bolt through joining with swing mechanism applies active force to spring, and this moment, spring was compressed, and guide pad has certain displacement in guide cylinder.The suspension bracket of this structure, guide cylinder part processed complex, assembling are loaded down with trivial details, and processing and matching requirements ratio of precision are higher, otherwise not only play bad guiding, also possibly cause suspension bracket stuck.
Summary of the invention
The purpose of the utility model provides the groove guiding type constant-force spring hanger that a kind of component processing is simple, be prone to assembling, no stuck phenomenon, overcomes the deficiency of existing technology.
The groove guiding type constant-force spring hanger of the utility model; Comprise the support that the front cover by the top board of two parallel support side plate, support side plate top and support side plate below that is positioned at the top is formed, two parallel rotor plates are arranged in the support and be rotationally connected, be positioned at a side of main shaft and the upper end of load bolt on the rotor plate and be rotationally connected through main shaft and support side plate; The opposite side that is positioned at main shaft on two rotor plates has connecting plate; The adjustment bolt is arranged on this connecting plate, and the adjustment bolt is rotationally connected between two rotor plates and on inner end and the arm-tie, and spring is arranged below front cover; There is pressing plate the lower end of spring; Upwards penetrated stay-bolt from the pressing plate center hole, the stay-bolt lower end has nut spacing, and the upper end of stay-bolt and the lower end of arm-tie are rotationally connected; Described stay-bolt upwards stretches out from the center hole of front cover; The joint of described stay-bolt and arm-tie is positioned at the top of described front cover, and stay-bolt is connected through bearing pin with arm-tie, and the two ends of bearing pin are positioned at the guiding groove of the vertical setting on the support side plate.
The groove guiding type constant-force spring hanger of the utility model, when operation, swing mechanism is if any a certain amount of swing; Spring is compressed, and bearing pin has a certain amount of moving up and down in guiding groove, has guaranteed moving up and down of pull bar and spring; Designs simplification assembles easy to maintenancely, has stopped stuck phenomenon.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
As shown in Figure 1: this suspension bracket top is support, and this support comprises two support side plate that are parallel to each other 22, is welded with top board 1 in the top of two support side plate 22, is processed with mounting hole on the top board 1, is used for fixing this suspension bracket.Bottom in support side plate 22 is welded with front cover 6.Support forms frame structure.
Be connected with swing mechanism on the support, concrete structure is following: two rotor plates that are parallel to each other 3 are arranged in the support inboard, be rotationally connected each other through main shaft 18 between rotor plate 3 and the support side plate 22.Be fixed with displacement indication bearing pin 2 in the outside of each rotor plate 3; Displacement indication bearing pin 2 just is positioned at the curve bath 21 on the support side plate 22; Guarantee that rotor plate 3 can relatively rotate several angle with respect to support side plate 22; When rotor plate 3 rotates with respect to support side plate 22 along main shaft 18, can indicate bearing pin 2 and curve bath 21 to carry out the spacing of displacement indication and rotor plate 3 rotation limit positions by displacement.
A side that on rotor plate 3, is positioned at main shaft 18 is rotationally connected through the upper end of coupling shaft 20 with load bolt 19.Be that load bolt 19 can rotate with respect to rotor plate 3 along coupling shaft 20.Screw thread is connected with degree of tightness nut 17 and is used to connect the lifted weight thing in the lower end of load bolt 19.
The opposite side that on two parallel rotor plates 3, is positioned at main shaft 18 has connecting plate, on this connecting plate, is installed with adjustment bolt 4, and adjustment bolt 4 is between two rotor plates 3.The inner of adjustment bolt 4 is rotationally connected through the top of roll pin and arm-tie 5.
Spring 7 is arranged below front cover 6, and there is pressing plate 10 lower end of spring 7, has upwards penetrated stay-bolt 11 from pressing plate 10 center holes, and stay-bolt 11 lower ends have nut 8 spacing.Stay-bolt 11 upwards stretches out from the center hole 14 of front cover 6; The joint of stay-bolt 11 and arm-tie 5 is positioned at the top of front cover 6; Stay-bolt 11 is connected through bearing pin 13 with arm-tie 5; The two ends of bearing pin 13 are positioned at the guiding groove 12 of the vertical setting on the support side plate 22, and bearing pin 13 can move up and down in guiding groove 12.Below front cover 6, be welded with the cylindrical shell 9 that covers on spring 7 outsides.
When operation, swing mechanism is if any a certain amount of swing, and spring 7 is compressed, and this moment, stay-bolt 11 was only made the vertical movement of above-below direction under the control of bearing pin 13, and bearing pin 13 moves up and down in guiding groove 12 simultaneously.Simple in structure, overcome stuck phenomenon.
