Document 3 corresponds to one motor driving four delivery hoses 32, and its pumping efficiency is improved, aiming at realizing a large flow pumping task of the medium.

From the analysis of stress angle, the common point of the documents 1, 2 and 3 is that the stress form of the rotor shaft is similar to that of a cantilever beam, namely, the rotor end is subjected to bending moment and torque in the rotating process of the rotating shaft, the deformation disturbance degree of the rotor end is large, the service life of the bearing is limited, the extrusion force applied to the hose is not only radial force but also axial force, the service life of the hose is limited, and the pumping efficiency is damaged.

The difficulty of hose assembly and disassembly in the document 1 is also existed in the documents 2 and 3, and the difficulty of bending the hose is obviously increased due to the larger specification, higher strength and higher toughness of the hose, and the hose assembly and disassembly of the large-flow pump is more difficult due to the integral structure of the pump head 3 or the annular groove 61 in the shell or the hose shield 60, and the difficulty of the hose assembly and disassembly in the document 3 is most prominent; in addition, the middle portion of the housing or hose shroud 60 is in a rotational fit with the rotor shaft, and heat generated during operation of the hose can also adversely affect the rotor shaft and bearings.

Detailed Description

As shown in fig. 1 and 2, a rotor frame 50 extending in the radial direction is arranged on a rotor shaft 40 horizontally arranged on a frame 10, a roller 60 is arranged at the outer end of the rotor frame 50 in the radial direction, a hose seat 20 is fixed on the frame 10, the hose seat 20 is integrally U-shaped, the cross section of the hose seat 20 is a groove with a built-in groove opening formed by a groove bottom 22 and groove walls 21 vertically arranged at two sides of the groove bottom 22, a hose 30 is arranged in the groove cavity along the groove cavity of the hose seat 20, the shaft core of the rotor shaft 40 coincides with the curvature center core of an arc section H of the hose seat 20, the surface of the roller 60 along with the rotation path of the rotor shaft 40 and the rotor frame 50 is coplanar with the surface of the hose 30, the roller 60 and the groove cavity of the hose seat 20 are matched to apply rolling action to the hose 30, the hose seat 20 is formed by at least two sections of parallel connection, the same-side groove walls on each section are kept coplanar when each section is mutually unfolded or enclosed, and the rotor shaft 40 positioned outside the rotor frame 50 is respectively rotatably supported by a first bearing seat 71 and a second bearing seat 72.

The main point of the invention is that the hose seat 20 is arranged in sections, and each section can be connected in a parallel way to form a U shape shown in figures 1, 3, 4 and 6; the device can also be in an unfolding shape which is formed by the rotation of each segment relative to the swing type, as shown in figures 1, 2 and 5; the engagement position is located on the outer part or the end part of the arc section H or the arc section, and the drawing gives an example that the engagement position is located on the arc section of the arc section H. The specific selection position and the number of the segment sections of the joint position can be determined by comprehensively considering the pipe diameter of the hose 30, the curvature radius of the set circular arc section H, the material of the hose 30 and other factors, and the purpose of fully expanding the hose seat 20 by using fewer joint positions so as to facilitate the bending of the hose 30 is achieved; the hose seat 20 is realized by arranging the rotor shaft 40 on the frame 10, as shown in fig. 1 and 2, the first bearing seat 71 and the second bearing seat 72 rotationally support the rotor shaft 40, and of course, bearings can be arranged between the first bearing seat 71 and the second bearing seat 72, and sliding bearings or rolling bearings can be selected according to requirements, so that a supporting scheme of a simple beam of the rotor shaft 40 is realized, the first bearing seat 71 and the second bearing seat 72 are arranged on the frame 10, and a scheme of arranging the first bearing seat 71 and the second bearing seat 72 on the hose seat 20 is avoided, on one hand, a scheme that a shaft seat of the rotor shaft is arranged in the middle part of a radial web of a pump shell of which the peripheral part is a hose groove seat in the prior art is thoroughly changed, thereby abandoning a cantilever beam arranging scheme of the rotor shaft in the prior art, ensuring that the hose seat 20 forms a segmented structure so as to form the change of the mutual position relationship of each segment of the hose seat 20.

When the hose 30 is initially installed, the sections are relatively swung to be rotated to the unfolded state shown in fig. 5, and it is to be noted that the unfolded opening shown in fig. 5 is not the unfolded limit opening, but can be larger according to the requirement, at this time, the hose 30 is directly placed in the upper groove cavity of each section of the hose seat 20, the hose 30 is in the unfolded state of a small curvature curve, then the sections are swung to be in the parallel connection state and finally enclosed to form a U shape, as shown in fig. 4 and 6, the hose 30 can be bent to the set curvature state under the constraint of the hose seat 20, as shown in fig. 3, the initial installation of the hose 30 is extremely convenient, and the hose 30 is placed in the groove cavity of the hose seat 20 to realize the subsequent further bending to the set curvature, thereby improving the installation efficiency of the hose 30 and saving time and labor; that is, the above scheme provided by the present invention avoids the scheme that the hose is directly bent to a state slightly larger than the set bending curvature and is embedded in the groove cavity of the complete integrated hose seat 20 at one time, and the bending is difficult due to the fact that the pipe diameter of the hose 30 of the high-flow hose pump is larger than or equal to 120mm, the bending is difficult due to the dead weight and the toughness, the bending is more difficult when the set bending curvature to be bent is larger, and the operation of shifting to the groove cavity of the hose seat 20 under the state of maintaining the bending is more difficult. The hose seat 20 in the invention is not only an essential component of a hose pump, but also can be used as a pipe bending tool when the hose 30 is assembled, and the hose seat 20 does not need to bear the function of a bearing seat of the rotor shaft 40, so that the rotor shaft 40 has the supporting condition of adopting a simple beam, the hose 30 in an overall stretching state or a small-curvature curved arc posture is arranged on the unfolded hose seat 20, and the hose 30 is synchronously embedded in the hose seat 20 along with the rotation of the hose seat 20 to a surrounding state, so that the assembly of the hose 30 and the hose seat 20 is realized.

It should be noted that, the hose base 20 is U-shaped overall and has a trough-shaped cross section, which means that it includes a U-shape formed by straight trough sections and arc sections H therebetween which are oppositely arranged, as shown in fig. 3, 4 and 6; the cross section of each section is in the same groove shape, as shown in fig. 3 and 4, namely, the groove bottom 22 and the groove wall 21 form the groove shape; the built-in notch means that the notch points to the inner side of the U-shaped area, as shown in fig. 4, the notch of the upper straight groove section 20A1 of the upper part faces downwards, the notch of the lower straight groove section 20B1 of the lower part faces upwards, the notch of the circular arc section H positioned on the right side of the upper straight groove section 20A1 and the lower straight groove section 20B1 points to the curvature center O-O of the circular arc section, and the shaft core of the rotor shaft 40 of the hose pump formed after assembly coincides with the curvature center O-O.

The selection of the segment positions of the segments of the hose base 20 is described in detail below.

As shown in the preferred embodiments of fig. 3, 4 and 5, the hose base 20 includes an upper hose base section 20A and a lower hose base section 20B, and the engagement position of the upper hose base section 20A and the lower hose base section 20B is located within the range of a semicircular arc section H; further, the engagement of the upper hose base section 20A and the lower hose base section 20B constituting the hose base 20 is located at the middle lower section of the circular arc section H.

Referring to fig. 5 and 6, the upper hose seat section 20A and the lower hose seat section 20B of the hose seat 20 are rotation members, the lower hose seat section 20B is a fixing member, the rotation range of the upper hose seat section 20A around the hinge shaft 25 is the position of the high and low dislocation positions at the two ends of the upper hose seat section 20A as shown in fig. 5 or the equal height position (not shown in the drawings), i.e. the opening degree, can be larger, in order to avoid the artificial bending of the large-diameter and high-toughness hose 30, the upper hose seat section 20A can continue to rotate by 60-90 degrees clockwise on the basis of the opening degree shown in fig. 5, so that the rotation range of the upper hose seat section 20A around the hinge shaft 25 is the equal height position or the position close to the equal height position at the two ends of the upper hose seat section 20A, and the hose 30 can be very easily placed in the groove cavities on the upper hose seat section 20A and the lower hose seat section 20B.

The angle of deployment shown in fig. 5 is suitable for use where the tube diameter of the hose 30 is slightly smaller because the hose 30 is slightly lighter in weight and less flexible.

In fig. 5 and 6, the upper hose seat section 20A is configured as a swinging member, and the lower hose seat section 20B is configured as a fixing member, and the upper hose seat section 20A in fig. 5 is rotated about 40-50 ° to an extended position relative to the forward engagement state shown in fig. 6, where it is convenient and labor-saving to insert the hose 30 into the groove cavities of the upper hose seat section 20A and the lower hose seat section 20B, i.e., the state shown in fig. 5 is the initial assembly position or the disassembly position of the hose 30 and the hose seat 20.

More specifically, the arc lower section H2 on the hose base lower section 20B is 1/3-1/4 of the arc section H, which can be understood as that the arc length or radian of the arc lower section H2 is 1/3-1/4 of the arc length or radian of the arc section H, the upper end of the arc upper section H1 on the hose base upper section 20A has an upper straight groove section 20A1 extending along the tangential direction thereof, and the lower end of the arc lower section H2 on the hose base lower section 20B has a lower straight groove section 20B1 extending along the tangential direction thereof. The arc lower section H2 is 1/3-1/4 of the arc section H, namely, the joint position of the arc lower section H2 and the arc upper section H1 is selected to be close to the bottom frame type frame 10, so that on one hand, the hose seat lower section 20B is favorably integrally fixed on the frame 10, and the reliability of the hose seat lower section is improved; on the other hand, the reinforcing support is directly arranged on the frame 10 to maintain the stability of the lower section 20B of the hose seat, and the reliability and stability of the connection of the joint position of the lower arc section H2 and the upper arc section H1 are improved, so that the following specific scheme is adopted:

the joint of the upper hose seat section 20A and the lower hose seat section 20B is hinged by a hinge shaft 25, the hinge shaft 25 is parallel to the rotor shaft 40, a swinging cylinder 90 is arranged between the upper hose seat section 20A and the frame 10, and the swinging cylinder 90 drives the upper hose seat section 20A to swing to an open position or a complete U-shaped enclosing position during the telescopic action.

The outer part of the arc lower section H2 on the hose seat lower section 20B is provided with a second support 24, the outer part of the lower end of the arc upper section H1 on the hose seat upper section 20A is provided with a first support 23, and a hinge shaft 25 is arranged in hinge holes on the first support 23 and the second support 24 in a penetrating way. It can be seen that the second support 24 has a fixed connection function on the one hand for the arc lower segment H2, and on the other hand has a function for supporting and hinging the arc upper segment H1.

The lower end of the arc upper section H1 of the upper hose seat section 20A is in abutting type parallel connection with the upper end of the arc lower section H2 of the lower hose seat section 20B. Therefore, the joint gap between the arc upper section H1 and the arc lower section H2 is ensured to be as small as possible and flush and smooth, and the shearing and bending damage to the hose 30 caused by overlarge joint gap and poor surface of the wall of the joint groove when the roller 60 rolls to the joint gap is avoided.

Because the invention needs to convey medium in large flow, the volume and the mass of the upper section 20A of the hose seat are large, the manual direct operation is dangerous and difficult, the invention provides the following preferred scheme, the hinge seat 27 is hinged with the piston rod end of the swinging cylinder 90 by the hinge pin 26 outside the upper section of the arc upper section H1 on the upper section 20A of the hose seat, the hinge pin 26 is parallel to the hinge shaft 25 and vertical to the telescopic direction of the swinging cylinder 90, the lower end of the cylinder body of the swinging cylinder 90 is hinged on the frame 10, and the hinge shaft core of the swinging cylinder 90 and the frame 10 is parallel to the hinge pin 26. By providing the swing cylinder 90 to drive the swing rotation of the upper hose base section 20A, not only is the swing cylinder 90 labor-saving and safe, but especially significant is that the upper hose base section 20A can be rotated and unfolded to a proper angular position and reliably limited in that position so as to cooperate with the disassembly and assembly of the hose 30, in fig. 6, the center-of-curvature core O-O is located at the upper left position of the hinge shaft 25, which is a stable working position where the upper hose base section 20A and the lower hose base section 20B are in flush engagement, so that at this time, both the rod-shaped cavity and the rodless cavity of the swing cylinder 90 can be in a normal pressure state or a non-pressure state, saving the energy consumption of hydraulic oil or pressure gas of the swing cylinder 90 is achieved, the above scheme is arranged that the swing cylinder 90 also has a safety guarantee, if the hydraulic system fails to have no pressure oil supply, the piston rod of the swing cylinder 90 is completely retracted into the cylinder body, as shown in fig. 5, the swing cylinder 90 provides a safe support for the upper hose base section 20A with the function of a rigid rod, and stably supports the upper hose base section 20A to be indexed to the maximum unfolded angular position. The swing cylinder 90 can be an air cylinder or an electric cylinder, and in view of the characteristics of the electric cylinder, namely, the main power supply provides energy, the problems of construction and maintenance of a pneumatic station or an oil pump station can be solved, and the electric cylinder is adopted to have more remarkable convenience.

The ends of the upper straight groove section 20A1 and the lower straight groove section 20B1 of the hose base 20 are provided with a fixing seat 32 of a hose joint tube 31 and a U-shaped clamp 33 for restraining the tube body of the hose 30. The tube end or tube end sections of the hose 30 are thus securely held captively.

Preferably, the first bearing housing 71 and the second bearing housing 72 for rotatably supporting the rotor shaft 40 are fixed to the first bearing housing bracket 711 and the second bearing housing bracket 721, respectively, and the hose base 20 is disposed between the first bearing housing bracket 711 and the second bearing housing bracket 721.

As shown in fig. 1, the rotor shaft 40 is provided with three rotors formed by the rotor frame 50 and the rollers 60, and correspondingly, the hose seat 20 and the hose 30 are also provided with three, the hose pump shown in fig. 1 can be regarded as a hose pump capable of working independently, and two groups of rotors near the end of the motor 1 and the speed reducer 2 are hidden in fig. 1, that is, the hose pump far away from the end of the motor 1 and the speed reducer 2 in fig. 1 and 2 is complete.

The arrangement of the three hose seats 20 and the hoses 30 has remarkable technical progress, namely, if the hoses 30 are damaged and cannot continue to work, other hoses can still continue to work, in addition, corresponding hoses are reasonably put into working according to the task requirements of pumping flow, and two ends of each hose 30 are respectively connected with the liquid inlet pipe A and the liquid outlet pipe B.

The above-mentioned scheme is to separate the first bearing seat 71, the second bearing seat 72 and the hose seat 20 in space, and the bearing seat in the prior art is not connected with the hose seat 20 through a web or a rod.

In order to reduce weight and ensure rigidity of the hose base 20, a reinforcing rib plate is disposed on the outer circumferential surface of the groove bottom 22 of the hose base 20, and specifically, the reinforcing rib plate includes a side rib plate 221 located at the edge side of the groove bottom 22 and a middle rib plate 222 located at the middle.

In order to ensure the stable position and posture of the upper section 20A of the hose base when pumping the medium, the end of the upper straight slot section 20A1 of the hose base 20 is provided with a support plate 28 connected with a rod frame 80, and the rod frame 80 is supported and connected on the frame 10. Under the combined action of the connection and fixation of the support plate 28 and the rod frame 80 and the hinged connection of the hinge shaft 25 and the first support 23 and the second support 24, the upper section 20A of the hose seat is stably fixed at a position which is in parallel connection with the lower section 20B of the hose seat.

Since the present application is mainly suitable for high-flow pumping service, the flexible pipe 30 has much larger flexibility and strength than that of the low-flow pump, the rolling force applied to the flexible pipe is also very large, the external force transmitted to the flexible pipe seat 20 is very large, and in order to keep the shape of the flexible pipe seat 20 stable, a solid constraint needs to be applied to the flexible pipe seat 20, namely, the end part of the upper straight groove section 20A1 of the flexible pipe seat 20 is provided with a support plate 28 connected with a rod frame 80, and the rod frame 80 is supported and connected on the frame 10. Thus, the rigidity and strength of the hose base 20 are increased by thickening materials without unilaterally, and the hose base 20 can be prepared in a lightweight manner by means of the rod frame 80, and the structural strength and rigidity of the hose base 20 are ensured. Under the combined action of the connection and fixation of the support plate 28 and the rod frame 80 and the hinged connection of the hinge shaft 25 and the first support 23 and the second support 24, the upper section 20A of the hose seat is stably fixed at a position which is in parallel connection with the lower section 20B of the hose seat.
