Abstract
A high precision constant-force spring box comprises a casing, an end plate and a top plate' wherein the housing positioned on the end plate is arranged with a constant-force spring back hanger. The utility model assembles the constant-force spring back hangers in the box body, and the loading quantum is large due to the top plate support conduit or device. The number and assembling of the constant-force spring back hangers in the constant-force spring box is different.This spring box is classified to the double assembling, the triple assembling, the quadruple assembling and the quintuple assembling, and every type is classified to several models as well. The loading quantum and bit shift of different models are different, and thereby the constant-force spring back hangers can be chosen according to different operating conditions. Several constant-force spring back hangers co-operate with one another to guarantee the constant-force spring box produce no additional stress and assure the safety of the device and conduit when bit shift is generated.
Description
Technical field
The utility model relates to the support device of heat distribution pipeline.
Background technique
The heat distribution pipeline system of industry such as thermoelectricity plant, chemical industry is in operation and can produces thermal walking, just need to use constant supporting spring hanger for bigger thermal walking, constant supporting spring hanger also is applicable to big load working condition simultaneously, and constant supporting spring hanger plays the effect to pipeline or balance of plant and damping.Existing constant supporting spring hanger exists volume to weigh greatly, and error is big, and deficiencies such as complexity are installed.When a plurality of suspension and supports were used in combination simultaneously, assembled on site was cumbersome.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of highi degree of accuracy constant force spring box, the invariance degree height, and load range is wide, and pipeline that is supported or equipment can not produce any additional stress to pipeline or equipment when thermal walking takes place.
The utility model highi degree of accuracy constant force spring box, it is characterized in that by casing, base plate and top board are formed, casing places on the base plate, be provided with constant-force spring hanger in the casing, described spring support hanging frame comprises housing, the load pipe is set in the housing, two rollers about install load pipe upper end, two rollers are supported on respectively on two cams, camshaft is set in the cam top and is installed on the housing, two hinged two counterbalance springs of cam difference, and the other end of counterbalance spring is bearing on the housing, the articulating point of cam and counterbalance spring with upper semisection and approaching with the lower semisection shape, the load pipe is with main spring outward, and the main spring lower end is the main spring cover, and two load adjustment bolts linked to each other with housing about the main spring cover passed through, load pipe top is added with supporting post, and supporting post is connected with casing top board outward.
The utility model is assembled in more than one constant-force spring hanger in the casing, and by top plate supporting pipeline or equipment, load capacity is bigger.The constant-force spring hanger quantity of constant force spring case inside and compound mode difference, the constant force spring case is divided into some types of two combinations, three combinations, four combinations and five combinations etc., and every type of specification difference by contained constant supporting spring hanger in the spring box is divided some kinds of models again.The loading force and the displacement of every kind of model have nothing in common with each other, and can select for use according to service condition.Several constant-force spring hangers cooperatively interact, and guarantee that the constant force spring case when being subjected to displacement, does not produce any additional stress, to guarantee the safety of equipment and pipeline.
The working principle of constant-force spring hanger is: pressure F passes to the load pipe through top board, and the load pipe directly acts on main spring, makes main spring produce power F1, and counterbalance spring also affacts on the load pipe for F2 by the synthetic back of the power of cam and roller.According to spring performance and the shape of cam and the variation of rotation angle of main spring and counterbalance spring, the F2 that makes a concerted effort of main spring power F1 and counterbalance spring changes in whole stroke range.But power F1 and F2's is that a constant masterpiece is used on the load pipe in whole stroke range with joint efforts, with pressure F balance.
When roller when the cam peak moves down, the F2 that makes a concerted effort of counterbalance spring reduces gradually, the power F1 of main spring increases gradually, the F2 with joint efforts of its counterbalance spring of making a concerted effort to deduct for the power F1 of main spring; In the neutral position, the F2 that makes a concerted effort of counterbalance spring is zero, and in this point, only main spring is born load; At lower position, the direction of the F2 that makes a concerted effort of counterbalance spring is opposite with the direction of main spring power F1, the F2 that makes a concerted effort of its counterbalance spring of making a concerted effort to deduct for the power F1 of main spring.So in whole stroke range, hanging force F is constant.
The working principle of whole constant force spring case is based on the working principle of constant-force spring hanger.
Advantage of the present utility model:
1. highi degree of accuracy constant force spring box model is complete, covers face width, and suitable load range is 2.5kN～2000kN; The displacement range that is suitable for is 0～300mm; Serviceability temperature is-20～220 ℃, and product scope has covered the possible needs of all users.
2, because spring box work loads in the piping displacement process is constant, so direction of displacement is to not influence of work loads.
3, the constant force spring case of same model, its work loads can be adjusted in very wide scope, and its work loads adjusting range can reach 100% of nominal operation load, but load transfers big the time, and displacement amount diminishes.
4, in the casing very in the camshaft of spring support hanging frame be placed on the top, cam curve is level and smooth, the shape of cam curve upper semisection and lower semisection is more approaching, design more becomes rationally, makes invariance degree better.
