Technical field

The utility model is that a kind of overhead traveling crane motor drives structure, refers in particular to a kind of motor drive structure that reduces overhead traveling crane running noise and promote the overhead traveling crane motion sensitivity.

Background technology

Motor by general overhead traveling crane drives structure, nothing more than adopting helical wheel induced way shown in Figure 1 or shown in Figure 2 with gear interlock drive structure, wherein helical wheel drives and mainly passes on power to overhead traveling crane to move wheel with the mutual interlock of two oblique shape gears, make overhead traveling crane be able to the front and back displacement, carry out part and hang; Because the weight of overhead traveling crane is quite heavy, make that the interlock of two oblique shape gears is stressed so become big, must be for solving this stressed problem with gear through heat treatment, begin to strengthen the strength of gear teeth and unlikely generation is stung tooth and ruptured; In addition, utilize metal gear as the interlock transmission, because of having the slit between gear, the collision sound when causing two gear interlocks in the running easily, and this slit can make overhead traveling crane uncontrollable accuracy in operation, and also more difficult in the control.

And face gear induced way shown in Figure 2, because the interlock mode of taking is all two gear interlocks and drives the overhead traveling crane displacement, identical problem with structural strength problem and running noise need to wait solution.

Summary of the invention

Main purpose of the present utility model is, provide a kind of overhead traveling crane motor to drive structure, this drive structure is connected between motor and the mobile wheel, is used for giving day car with the rotational power of motor the running sound when being minimized the overhead traveling crane displacement when making the transmission running and lifting overhead traveling crane motion sensitivity.

For achieving the above object, the utility model discloses a kind of overhead traveling crane motor and drive structure, by an adjustment seat that is articulated in the structural mobile wheel of overhead traveling crane, a motor and sets up from the overhead traveling crane connection for motor is fixedly arranged on; It is characterized in that:

Move wheel, have chute and some driving grooves for drive belt cover Shu Dingwei, this driving groove has the drive belt of groove through cover Shu Ruogan, is connected to the driven wheel that motor protrudes out axle center bar front end, on its driven wheel wheel face also identical be formed with the driving groove that waits number and correspondence its move wheel;

This motor lower end base utilizes check screw and is installed with on an adjustment seat, wherein this adjustment seat comprises a platform and connects the hinge of overhead traveling crane and the adjusting lever that the platform front end wears interlock at the platform tail end, this adjusting lever has two screw rods and two movable axostylus axostyles, wherein this screw rod wore platform, mat make rise the platform front end and with the hinge of tail end, platform is an inclination angle kenel.

By said structure, the utility model can be realized following technique effect:

1, moves wheel with the axostylus axostyle of drive belt interlock to motor output rotational power, the running sound when being minimized the overhead traveling crane displacement during transmission running.

2, motor is to be configured in overhead traveling crane to extend on the adjustment seat that sets up, and can be adjusted the stay bolt elasticity of motor drive belt with adjusting seat displacement up and down.

3, it is one-body molded made with synthetic metal to move wheel, can reduce and move the degree of wear that wheel is caused by the drive belt transmission, improves service life.

The specific embodiment

The utility model is that a kind of overhead traveling crane motor drives structure, be used for giving day car with the rotational power of motor, (seeing also Fig. 3, Fig. 4) mainly comprises one and is articulated in overhead traveling crane 1 structural mobile wheel 2 and a motor 3 and is connected the adjustment seat 4 that sets up with being fixedly arranged on for motor 3 from overhead traveling crane; Wherein, this overhead traveling crane 1 is become by the reinforcing bar welding, respectively is formed with an accommodation chamber 10 in quadripolar corners, and each moves wheel 2 for one and is articulated in the accommodation chamber 10 (as Fig. 4) with axle center 20; And the built-in mobile wheel 2 in an end angle wherein, include chute 21 and some driving grooves 22 especially for drive belt 5 cover Shu Dingwei, this driving groove 22 can have the drive belt 5 of groove 50 through cover Shu Ruogan, be connected to the driven wheel 31 that motor 3 protrudes out axle center bar 30 front ends, also identically on its driven wheel 31 wheel faces the driving groove of number such as be formed with and corresponding its moves wheel 2, make drive belt 5 be fixed in the form of a ring moving 31 of wheel 2 and motor 3 driven wheels, mat makes that interlock moves wheel 2 rotations with motor 3 outputting rotary powers;

These motor 3 lower end bases 32 utilize check screw 33 and are installed with on an adjustment seat 4, wherein this adjustment seat 4 comprises a platform 40 and connects the hinge 41 of overhead traveling crane 1 and the adjusting lever 42 that platform 40 front ends wear interlock at platform 40 tail ends, this adjusting lever 42 has two screw rods 43 and two movable axostylus axostyles 44 (as Fig. 3), wherein this screw rod 43 wore platform 40, and in screw rod sheathed packing ring 45 about in the of 43,450 and one plus-minus screw 46,460, and the extension of screw rod 43 lower ends is connected to movable axostylus axostyle 44, mat makes to be risen platform 40 front ends and is pivot point with the hinge 41 of tail end, platform 40 is an inclination angle kenel, 3 in this motor is strained drive belt 5 with platform 40 angles, makes drive belt 5 elasticities obtain control adjustment by this.

This overhead traveling crane 1 is to move the slide rail 6 that wheel 2 chutes that have 21 are positioned both sides, factory building top, overhead traveling crane 1 can be moved in slide rail 6 scopes, when desiring operation crown block 1 displacement, then with the downward controller that extends of overhead traveling crane 1 electric connection, starter motor 3 runnings, motor 3 drives 31 rotations of front end driven wheels through axle center bar 30, with the power of driven wheel 31 rotations, orders about drive belt 5 and drives lower ends and move wheel 2 and drive overhead traveling crane displacement (consulting Fig. 5) with its rotation.

When overhead traveling crane used to a period of time; drive belt 5 can make elasticity seem slack and undisciplined because of long-term the stretching usually; when influencing the sensitivity of controlling overhead traveling crane (consulting Fig. 6); then can utilize the adjusting lever 42 of platform 40; screw rod 43 upper end plus-minus screws 46 are unclasped; utilize lower end plus-minus screw 460 to be rotated adjustment again; this platform 40 is rotated up by plus-minus screw 460 and the hoisting depth that makes progress; make synchronously motor 3 height with rising; and then with slack and undisciplined drive belt 5 stay bolt once more; improve the interlock tightness, recover preferable interlock control sensitivity.
