Description

A kind of Spring balancer

Technical field

The utility model relates to machinery manufacturing technology fields, more particularly to a kind of Spring balancer.

Background technique

Spring balancer is widely used on various flow production lines, is mainly made using the energy of its internal wind spring savings The gravity of the article hung on the pulling force and balancer of wirerope is cancelled out each other, and article is made to be in state of weightlessness, can be upper and lower It moves freely.Especially for the auxiliary tool of some large sizes, can be guaranteed using balancer it is more convenient using auxiliary tool, It improves work efficiency and work quality, reduces labor intensity.Therefore automobile, tractor, household electric are widely used in In the processing line of industries such as device and machine manufacture.But some operation items need to infuse in the use process of Spring balancer Meaning, for example, need to transfer the upright position loosening tool again that furthers when operative employee laterally moves to gradient and is more than 30 °, otherwise easily cause Wirerope mistake slot is stuck.

And the free end of existing Spring balancer wirerope is directly on the shell most of at balancer shell A rectangular long hole 6, the prompting of no any limit angle are opened up, but how much can all be produced during using Spring balancer The gradient of raw tool offsets, operative employee can only lean on after range estimation or micro-judgment gradient the operation for carrying out next step again, however this It tends to misjudgment and again in the case where misoperation, for new hand's use, is easy for causing safety Accident, while equipment can also be damaged.

Summary of the invention

The purpose of the utility model is to provide a kind of Spring balancer, increase gradient operation is reminded, and makes to operate simpler Safety, while also improving the safety of equipment.

The technical solution to solve the above problems is: a kind of Spring balancer, the balance in shell, shell including balancer The upper hooks and lower part suspension hook of device ontology and setting balancer outside the shell, the intrinsic wirerope of balancer from By holding the shell across balancer to be connected with lower part suspension hook；The free end of the wirerope passes through lower section setting at balancer shell There is limiting device, the limiting device is hollow tetragonous stage body, and the section of the hollow tetragonous stage body is rectangle, the limit The angle that position each side of device and limiting device bottom surface are formed is α, the value range of the α angle are as follows: 90 ° of 60 °≤α <.

Preferably, the free end of the four edges and wirerope on the upper bottom surface side of the limiting device passes through at balancer shell Edge coincide.

Preferably, the free end of the limiting device and the wirerope passes through the knot that is integrally formed at balancer shell Structure.

Preferably, the outer surface of the limiting device is coated with one layer of rubber.

Due to the adoption of the above technical scheme, a kind of Spring balancer of the utility model have following characteristics and the utility model has the advantages that The utility model has structure simple, easy to use and operate, is limited by passing through to increase at balancer shell in the free end of steel cable Position device, convenient for observation remind, the gradient for facilitating operative employee correctly to judge that tool laterally moves to whether more than 30 °, avoid because Cause wirerope mistake slot stuck when the excessive loosening tool of gradient, while the outer surface of limiting device is coated with one layer of rubber, avoids Direct friction between balancer wirerope and balancer shell, extends the service life of balancer, reduces balancer Use cost.

Detailed description of the invention

Fig. 2 is the structural schematic diagram of the limiting device of the utility model；

Fig. 3 is the bottom view of the limiting device of the utility model.

In figure:

1- shell, 2- upper hooks, 3- wirerope, the lower part 4- suspension hook, 5- limiting device, 6- long hole.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.

Balancer ontology and setting as shown in Figure 1, a kind of Spring balancer, in shell 1, shell including balancer The upper hooks 2 and lower part suspension hook 4 of balancer outside the shell, the free end of the intrinsic wirerope 3 of balancer pass through flat The shell 1 of weighing apparatus is connected with lower part suspension hook 4；The free end of the wirerope passes through lower section at balancer shell and is provided with limit dress Set 5.The limiting device is hollow tetragonous stage body, and referring to figs. 2 and 3, the section of the hollow tetragonous stage body is in rectangular Shape；The four edges of the upper bottom surface of the limiting device and the free end of wirerope pass through the side of (i.e. long hole 6) at balancer shell Edge coincides.The free end of the limiting device and the wirerope passes through to be an integral molding structure at balancer shell.It is described The angle that the bottom surface of each side of limiting device 5 and limiting device 5 is formed is α, the value range of the α angle are as follows: 60 °≤α 90 ° of <.By the formula of angle sum of a triangle it is found that the maximum slope that the angle β i.e. tool in Fig. 2 laterally move to, the maximum Gradient is less than or equal to 30 °.The free end of the wirerope passes through hollow tetragonous stage body and is connected with lower part suspension hook.

The outer surface of the limiting device is coated with one layer of rubber.

The application method of the limiting device 5 of the utility model is exemplified below: for example, the limit of Spring balancer The angle that the bottom surface of each side of device 5 and limiting device 5 is formed is that α is equal to 60 °, the Spring balancer when in use, lower part 4 hanging tool of suspension hook, the gradient that the transverse direction of specification tool moves to as long as observing wirerope 3 in 5 inner cavity of limiting device are Safety, but if observing that wirerope is pierced by along certain one side of limiting device 5 or outside limiting device 5, then illustrates The gradient that the transverse direction of tool moves to has exceeded safe range, needs that tool is transferred the Spring balancer that furthers by code requirement vertical The operation of loosening tool is carried out at position, again to avoid causing wirerope mistake slot stuck.

The Spring balancer of the utility model can allow operative employee to judge whether to need rapidly due to having installed limiting device 5 additional Tool is transferred the upright position for the Spring balancer that furthers, can be saved in the range of allowing gradient (being no more than 30 °) The operating procedure transferred and furthered is stated, operating process is simplified, improves work efficiency, while also ensuring the safety of equipment.

The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model Within enclosing.
